tests: don't compare MTIME header of gzip file

The gzip header contains a MTIME part (Modification TIME).
http://www.zlib.org/rfc-gzip.html
Because is takes a little bit of time, from one fill_archive call to the next,
this part may differ and fail the test from time to time.
So we should not include that part in the comparison.
