rust: Make the hg-cpython crate default to Python 3

This default is used when running `cargo` manually such as for `cargo test`.
`setup.py` and `Makefile` both configure the Python major version explicitly.

# This script gets executed on container start. Its job is to set up
# the Mercurial environment and invoke the server.

# Mercurial can be started in two modes.
# If the MERCURIAL_SOURCE environment variable is set and it points to a
# Mercurial source directory, we will install Mercurial from that directory.
# Otherwise, we download the Mercurial source and install it manually.
