status: if ui.relative-paths=no, don't use relative paths even with patterns

Without ui.relative-paths or command.status.relative set, you get this
behavior:

  hgext$ hg st
  M hgext/narrow/narrowrepo.py
  hgext$ hg st .
  M narrow/narrowrepo.py
  hgext$ hg st narrow
  M narrow/narrowrepo.py

I think it's surprising that some of those produce relative paths. I
suspect it works that way because "hg st ." was an easy way of getting
relative paths. Perhaps not much thought was given to how it should
behave when the pattern was not ".". It also feels wrong to conflate
the request for relative patterns with matching of of patterns.

Since we can now start fresh and define the behavior of
ui.relative-paths as we want, I suggest we make ui.relative-paths=no
consistently not give relative paths. So that's what this paths starts
doing for `hg status`.

  $ cd $TESTDIR/../contrib/fuzz

which(1) could exit nonzero, but that's fine because we'll still end
up without a valid executable, so we don't need to check $? here.

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