populate-initrd: handle themes with subdirs

Not all distros use the upstream plymouth-populate-initrd
script to populate their initramfs.  As a consequence,
some themes have been developed that use subdirectories,
(which is not supported by plymouth-populate-initrd).

This commit adds support for that feature, so that
preexisting themes get properly installed.
