Set commit time to ZipArchiveEntry

Archived zip files for a same commit have different MD5 hash because
mdate and mdate in the header of zip entries are not specified. In
this case, Commons Compress sets an archived time.

In the original git implementation, it's set a commit time:
e2b2d6a172/archive.c (L378)

By this fix, archive command sets the commit time to ZipArchiveEntry
when RevCommit is given as an archiving target.
