git-svn: unlink index files that were globbed, too

commit 3157dd9e89 (git-svn: unlink
internal index files after operations) introduced unlinking
index files after fetching.  However, this missed indices for
refs that were created by globbing branches and tags.  This will
track all refs we ever touch during a fetch and unlink them at
exit time.
