Summary: Make `import edenscm` take care of `sys.path` so as long as `import edenscm` works, 3rd party pure Python dependencies and edenscmnative should be importable. This reduces adhoc sys.path handling in testutil.dott, and fixes an issue where testing on Windows where `testuitl.dott` fails to run hg commands due to missing 3rd party dependencies (because `edenscm.mercurial.entrypoint.run` is not called, and edenscmdeps.zip is not in sys.path).
