wumpus: update livecheck

The existing `livecheck` block for `wumpus` only works intermittently
because the upstream server for the catb.org homepage can take
longer than the ten-second livecheck timeout. This updates the
`livecheck` block to check the Git tags from the `head` repository
as a workaround.
