test-subrepo-recursion: more aggressively regex 'unzip -l' output for 10.10

The output on 10.10 looks like this:

    Length     Date   Time    Name
   --------    ----   ----    ----
        172  01-01-80 00:00   .hg_archival.txt
         10  01-01-80 00:00   .hgsub
         45  01-01-80 00:00   .hgsubstate
          3  01-01-80 00:00   x.txt
         10  01-01-80 00:00   foo/.hgsub
         45  01-01-80 00:00   foo/.hgsubstate
          9  01-01-80 00:00   foo/y.txt
          9  01-01-80 00:00   foo/bar/z.txt
   --------                   -------
        303                   8 files

(2 digit year, shorter -- separators and closer columns).  We don't care about
any of that, so ignore it.
