description:
Fix extraction of section number and machine architecture from man pages.
With the latest API, mdoc_validate()/man_validate() needs to be called before
reading the roff_man.meta field, otherwise it is NULL.

Also, if a man page doesn't specify machine architecture, don't default to '?'
, let it be stored as null in the db. Otherwise, the output of apropos(1) shows
the names of the results as \?/<title>
