c5bd8af65e system: add options for /bin /sbin and /lib to be symlinks into /usr
systemd is increasingly expecting things to live in /usr/bin, /usr/sbin
or /usr/lib nad not in /bin, /sbin or /lib. It has inherited those
expectations from a Fedora change:
    https://fedoraproject.org/wiki/Features/UsrMove

Note however, that systemd does support /usr being on a separate
filesystem; it just expects an initramfs to mount it before the final
switchroot over to the actual rootfs.

But the traditional use-case for Buildroot is not to boot with an
initramfs; although that is totally feasible, that's probably not what
is commonly done in the vast majority of cases.

However, a lot of packages still install stuff directly into /bin,
/sbin or /lib, which systemd may need early-on in the boot process,
even before it may have a chance to mount /usr. Even though we can
tell systemd, at configure-time, where it should expect programs to
be at runtime, it does not make sense to go head-first against an
upstream wa^Hill.

Add an option so that /bin, /sbin and /lib be symlinks to /usr/bin
and /usr/sbin. That option is forcibly enabled when the init system
is systemd.

Note: we need not handle /lib32 or /lib64, as they already are symlinks
to /lib, which means they will automatically be redirected to /usr/lib,
as /usr/lib32 and /usr/lib64 already are.

Furthermore, this means we're no longer supporting a split-usr setup, so
the corresponding configure options have been removed as well for
systemd and, when using a merged /usr, for eudev as well.

In Buildroot, we decided (with this patch) not to support a split-usr
when systemd is used as an init system. This is a design decision, not
a systemd issue. Thus the select is with BR2_INIT_SYSTEMD rather than
with BR2_PACKAGE_SYSTEMD.

0291f7c220 skeleton: use backtick instead of $(shell ...) make function
Only the instance for setting the root password is changed. The
instance in SYSTEM_GETTY is harmless since it just uses echo and tail.

If SKELETON_TARGET_GENERIC_ROOT_PASSWD is passed as a hashed password
by the user, it contains $, so the '-quotes are needed. If it is not,
we need the backtick to be expanded so "-quotes are needed. Therefore,
the quoting is moved to the definition of SYSTEM_ROOT_PASSWORD.

7a6b83a211 skeleton: New package
Create a proper package for the skeleton.

The main Makefile is modified to remove the skeleton support.
The 'dirs' target, will create the $(TARGET_DIR).
The file 'output/target/.root' doesn't exists anymore, as there's no
Make rule to statisfy.

The infrastructure are modified to filter host-skeleton.
It's needed becauses the host-dependencies are derived from the
dependencies of the target package where 'host-' is preprended to the
depedency name.

In the pkg-generic we add skeleton as a dependency to every package.

The whole system/system.mk is now removed at the profit of
package/skeleton/skeleton.mk

[Thomas:
  - rebase on top of master and fix some minor conflicts
  - remove the 'select BR2_PACKAGE_SKELETON' in
    BR2_ROOTFS_SKELETON_DEFAULT and BR2_ROOTFS_SKELETON_CUSTOM, since
    anyway the skeleton package is always enabled.
  - fixup a few mistakes in the getty handling due to misnamed
    variables.]
