Removing refs to `github.com/marstr/randname`

There are some portability concerns with adopting `randname`. Chiefly,
it would mean that dictionaries of words to use for randomness would
need to be dristributed with the mirrorcat executable. Given that we can
achieve the same effect, but with less readable names using `ioutil`,
this change is pretty important.
