[PATCH] Update sgml to generate reproducible manpages

[Hu Keping]

Prior to this patch, we failed to recreate bit-by-bit identical
copies of wpa_supplicant because it doesn't generate reproducible manpages.

Since the latest version(0.6.14-3 or new) of docbook-utils have already
support getting the date from sgml file [1], it is possible to make some
progress on the "reproducible builds" effort [2].
