localrepo: do not cache auditor/nofsauditor which would make reference cycle

Before, self.auditor and self.nofsauditor held self through self._checknested,
and the following code couldn't free a repo by ref-counting.

  def main():
      repo = localrepo.localrepository(uimod.ui(), '../testrepos/hello')
  main()

With this change, the cache of the nofsauditor is limited to a single match
session. I think that's okay as the nofsauditor doesn't do any filesystem
access. Alternatively, maybe we can remove the callback from nofsauditor
since it isn't used unless realfs=True, but I have no idea whether it is
a bug or not.
