9c67af2c52 system/skeleton: use uid/gid 65534 for nobody/nogroup
As recently discussed on lwn.net: https://lwn.net/Articles/695478/

The kernel has special behaviour for uid/gid 65534:

1. The kernel maps UIDs > 65535 to it when some subsystem/API/fs
   only supports 16bit UIDs, but a 32bit UID is passed to it.

2. it's used by the kernel's user namespacing as the internal UID
   that external UIDs are mapped to that don't have any local mapping.

3. It's used by NFS for all user IDs that cannot be mapped locally if
   UID mapping is enabled.

Most distributions already map (or are in the progress of changing)
nobody/nogroup to the 65534 uid/gid, so lets do so as well.

d1a4aa9c87 system/skeleton: drop proxy user
AFAIK no package uses it and even if it did it would belong there.
And it's not a standard user either.

aa66ce2d57 openssh: drop user from skeleton
The sshd privilege drop user doesn't belong in the skeleton, it's
exclusively used by OpenSSH.

We dropped the hal package quite some time ago, and it's not even a
properly created user.

b4f6274585 Remove user "default"
User "default" with no password has been around for long time, but not
used within buildroot. Since we now have BR2_ROOTFS_USERS_TABLES it is
no longer needed.

6c3e3ad419 New top-level directory: system
This directory groups the following elements:
 * the default root filesystem skeleton
 * the default device tables
 * the Config.in options for system configuration (UART port for
   getty, system hostname, etc.)
 * the make rules to apply the system configuration options

Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.

As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.
