Use file's mtime as mtime for its extended header.
This makes two pax archives binary equivalent if they
have the same contents and care is taken to make extended
headers otherwise reproducible, e.g. by using:
Proposed by Michael D. Adams <mdmkolbe@gmail.com>.

Use current time stamp as mtime for global headers.

to the archive.
