File timestamp (and file name) have no use for pci.ids.gz
This allow to produce the exact same file even when compiled at different times.
That make paranoid happy.
Even gzip-1.2.4 from 1993 support -n option
Concerning the fact that -n did not include file name, that does not matter
unless the compressed file is moved under a different name and later -N option
is used to open the file.
