do_split_packages() returns the list of packages that it created, so the
output from the final call to do_split_packages (that creates lib%s) should
be exactly what you need to create a metapackage.

(it currently returns duplicates if multiple files are packages, but this
doesn't cause a problem for metapackage dependencies)
