wic: Avoid creating invalid pseudo directory

If the source of the rootfs is not a bitbake cooked image, or it is not
pointing to the root of one, we call pseudo again, which will produce
a new pseudo folder at rootfs/../pseudo

Eg:

part /etc --source rootfs --rootfs-dir=${IMAGE_ROOTFS}/home --fstype=ext4
