Subject: [PATCH] fstab: do not mount and fsck from fstab if using systemd

If using systemd in initramfs, we could run into a race condition when
dracut and systemd both are trying to mount and run fsck for the same
filesystem, and mount or fsck could be a failure.

To fix such failure, we should use systemd to mount/fsck from /etc/fstab
only.

v2: check $DRACUT_SYSTEMD suggested by Alexander Tsoy
