Making /var/run and /run symlinks to /tmp is bad since the underlying
tmpfs filesystem is mode 1777 which leads to possible security attack
vectors via badly owned/mask-mode pidfiles and state files residing there.
So make /run a proper directory with /var/run symlinked to it.
Eventually all startup scripts and state info should be pointed to /run
directly as per the linux fhs and good practice.
Add a tmpfs filesystem entry for /run so that busybox inittab, systemv
inittab and systemd automount mounts it there to avoid breaking the
system.
While at it fix inconsistent spacing in /etc/fstab by using tabs and
drop the "static file system information" header whatever that means.

ramfs (which is used instead of tmpfs if CONFIG_SHMEM isn't enabled in the
kernel configuration), defaults to mode 0755 instead of 01777 like tmpfs
uses.
/tmp should be world writable and sticky, so explictly enforce the mode so
ramfs users gets it correct instead of relying on the defaults.

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.
