setup: make the name of the main script flexible

Browse Source 
Summary:
Previously, the main script is hard-coded as `hg`. We use a wrapper named
`hg` for logging. Therefore make the name more flexible by reading `HGNAME`.
The name is enforced starting with `hg` and cannot have strange characters.

Test Plan:
`HGNAME=hg-foobar python setup.py install --user`. Make sure the `hg-foobar`
script gets installed in `~/.local/bin`, has the correct `libdir` set, is
working, and the working copy does not have `hg-foobar`.

Also make sure `make local` does not write `$HGNAME` in the working copy.
