D3114: tests: work around potential repo incompatibility

REVISION SUMMARY
  test-run-tests.t invokes run-tests.py. But custom extensions providing
  new repo requirements may be in play and may not get inherited by the
  new run-tests.py. We ensure our repo is created with a vanilla config
  to mitigate extension-caused badness.

REPOSITORY
  rHG Mercurial

 ===================================
-  $ hg init inuse

+Extensions aren't inherited by the invoked run-tests.py. An extension
+introducing a repository requirement could cause this to fail. So we force
+HGRCPATH to get a clean environment.

+  $ HGRCPATH= hg init inuse
