bpo-45863: tarfile: don't zero out header fields unnecessarily (GH-29693)
Numeric fields of type float, notably mtime, can't be represented
exactly in the ustar header, so the pax header is used. But it is
helpful to set them to the nearest int (i.e. second rather than
nanosecond precision mtimes) in the ustar header as well, for the
benefit of unarchivers that don't understand the pax header.
Add test for tarfile.TarInfo.create_pax_header to confirm correct
behaviour.
