qtestblacklist: only generate the distro and version once

We were looking up distro and version, in order to conditionally add
them to keywords if missing, on every keyword line of each BLACKLIST
that we parsed.  In particular, this meant the static holding the list
of keywords couldn't be const.  Move the distro-handling to an
intemediary function that adds to the raw keywords and supplies
one-off initialization for the list of conditions to match.
