plugins: call bootmisc:bootclean() in HOOK_MOUNT_POST
plugins: call bootmisc:bootclean() in HOOK_MOUNT_POST

Before this patch bootclean() ran first in setup() which caused to to
remove the entire /var/run/finit directory, and other files as well,
created earlier.  Only possible fix is to split clean and setup in
two and make sure to call clean as soon as we've mounted everything.

Note: this introduces a new behavior, and anyone hooking into the
      same point to do good-stuff(tm) may be affected by this.
