git-archive: don't die when repository uses subprojects

Both archive-tar and archive-zip needed to be taught about subprojects.
The tar function died when trying to read the subproject commit object,
while the zip function reported "unsupported file mode".

This fixes both by representing the subproject as an empty directory.
