wic: Fix partition files UIDs on multi rootfs images
When a wks makes reference to multiple rootfs, libspeudo data is not
properly chossen. This results in filesystems with invalid UIDs for all
the files.
This can be tested with this .wks file:
part / --source rootfs --fstype=ext4 --rootfs-dir=core-image-base
part /mnt/data1/ --fstype=ext4 --source rootfs --rootfs-dir=core-image-minimal
part /mnt/data2/ --fstype=ext4 --source rootfs --rootfs-dir=core-image-minimal
And this script
$bitbake core-image-minimal core-image-base syslinux
$losetup --partscan --find --read-only --show test*direct
$sudo mount /dev/loop0p1 /mnt
$ls -lan /mnt
