blacklist get-rep: re-implement to query repos instead of blacklist.txt

Rationale: https://lists.parabola.nu/pipermail/dev/2017-October/005936.html

This makes get-rep a general-purpose tool for finding replacements and
providers of any package, not just blacklisted-ones. It works equally
well reading from full blacklist.txt lines, just pkgname lines, and
unwittingly; a single line with many pkgnames.

Some caveats for further discussion:

 - This changes behavior from showing just one replacement/provider to
   _all_ replacements and providers (including pkgname itself) in the repos.

 - By "repos" I mean the repos the executing machine is configured to
   access. This could be changed in the future with `expac --config`
   if more package databases are desired (e.g. different
   architecture).

 - Results are shown using the "repo/pkgname ..." format rather than
   just "pkgname ...". I think this makes the program more useful.

 - Results aren't reordered to ensure that the first provider of
   pkgname is pkgname itself. Order will be as expected otherwise, by
   virtue of expac parsing repos in order.
