meta-lg: systemd-machine-units: put files into correct directory to include them really

meta-hp: initramfs-boot-android: create missing directories

LVM requires /var/lock to be present which now symlinks to /run/lock which isn't created
by anybody in our initramfs as no real init system is running which would care about it.
Without this fix the init script is unable to mount the root partition
