[OE-core] [PATCH 3/3] initscripts: disable mountall.sh for busybox init

[wenzong.fan at windriver.com]

From: Wenzong Fan <wenzong.fan at windriver.com>

Disable 'mountall.sh' to avoid system halt while the init manager is
set as 'busybox'.

In busybox init, the 'SIGUSR1' was handled as 'halt', calling to the
'mountall.sh' would trigger the signal with:
  + kill -USR1 1

This works fine for sysvinit but will fail with the busybox init.

As a replacement, busybox provides 'inittab' to mount all of those:
  ::sysinit:/bin/mount -t proc proc /proc
  ::sysinit:/bin/mount -t sysfs sysfs /sys
  ::sysinit:/bin/mount -t devtmpfs devtmpfs /dev
  ::sysinit:/bin/mount -o remount,rw /
  ::sysinit:/bin/mkdir -p /dev/pts
  ::sysinit:/bin/mount -t devpts devpts /dev/pts
  ::sysinit:/bin/mount -a
