Summary:
The SCM wrappers do not have a reliable and easy way of detecting the repo root. For instance, if someone does hg log /full/path/to/repo/content, we cannot actually determine that /full/path/to/repo is the repo root. We have to somehow integrate an overly large portion of mercurial's commmand parsing infrastrastructure to accomplish this.
However, since mercurial knows the repo root, just extract that knowledge and send it down to the client.
Test Plan:
```

chg: enabled by /etc/mercurial/usechg

Without this change, the repo would be "unknown-repo":
```
[dev8692]:~> USE_DIST_HG= FB_HG_DIAGS= hg log --config 'sampling.key.reporootlog=perfpipe_dev_command_timers' work/facebook-hg-rpms/smoketest.sh 2>&1 | grep repo
