Move mounting of debugfs back to chromeos_startup script

Since boards built without debugd do not have debugfs-access user and
group, the mount command for debugfs will fail, causing the script to
exit early before /run is mounted as tmpfs.  Move the mount command
back to chromeos_startup, which will continue execution after the
mount.

BUG=chromium:388394
TEST=panther boots with debugfs mounted.
TEST=duck boots, /run is mounted as tmpfs.
