Upstream-Status: Inappropriate [embedded specific]

The FHS indicates that /etc must be capable of being mounted R/O.

The FHS also indicates that lock files belong in /var/lock, and /var must
be R/W as soon as possible during boot.

This patch moves the mtab lock file from the potentially R/O /etc, to the
R/W /var/lock area.  This lock file is used when mounting disks and making
other mount adjustments.  The _PATH_MOUNTED_TMP is not adjusted, as failing
to write to this file does not cause any functional limitations.

(Note, if /etc is R/O, then /etc/mtab should be a symlink to /proc/mounts)
