Accept empty file list in fsverity_manifest_generator

By accepting empty file list, it allows the build rule to generate the
build_manifest.pb unconditionally. Consequently, the consuming code in
composd won't need to handle the empty case (which requires parsing the
zip entry if it's done on the host side).
