From: Chen Qi <Qi.Chen@windriver.com>

Previously, if no unification filesystem mechanism is compiled into kernel
and we are booting a live image, it's very likely the image cannot run correctly.

Now if we have 'read-only-rootfs' in IMAGE_FEATURES, the live image could start
correctly even if there's no unionfs like feature compiled in kernel.

  populate-volatile.sh: use $ROOT_DIR/var/volatile/tmp as TMPDIR
  runqemu-internal: fix to start X correctly in live images
  initscripts: use a uniform way to handle directories in read-only
    rootfs
  irda-utils: make /etc/sysconfig writable in read-only rootfs
