[OE-core] [PATCH 07/13] rootfs-postcommands.bbclass: add inittab tweak to read_only_rootfs_hook()

[Andre McCurdy]

It's not clear that we actually need to call mount -o remount,XX from
the busybox-inittab inittab at all, but as we currently do, let's
respect read-only-rootfs in IMAGE_FEATURES and not remount / as rw.
