locate: explicitly use dirstate.matches() for working copy
`hg locate` is odd in that it includes files that have been removed
from the working copy. It relies on workingctx.matches() for that. I
want to make workingctx.matches() not include removed files, so this
patch makes `hg locate` handle the working copy differently instead.

Just run the fuzzers for five seconds each to verify it works at all.
