ci: shard the test run on mac os X
This should comes with some benefit:
- spread the load across more runner,
- reduce the real-time CI run,
- reduce the "retry" run when we need them.
We start with the Mac jobs, but that would be tremendously useful for Windows
too.
For linux, we need to reduce the startup overhead for this to be worth it.
Building smaller image and speeding up clone should help with that.

# By default we build a .deb where the native components are built with the
# current "default" version of py3 on the build machine. If you wish to build a
# .deb that has native components built for multiple versions of py3:
#
# 1. install python3.x and python3.x-dev for each version you want
# 2. set DEB_HG_MULTI_VERSION=1 or DEB_HG_PYTHON_VERSIONS in your environment
# (if both are set, DEB_HG_PYTHON_VERSIONS has precedence)
#
# If you choose `DEB_HG_MULTI_VERSION=1`, it will build for every "supported"
# version of py3 that's installed on the build machine. This may not be equal to
# the actual versions that are installed, see the comment above where we set
# DEB_HG_PYTHON_VERSIONS below. If you choose to set `DEB_HG_PYTHON_VERSIONS`
# yourself, set it to a space-separated string of python version numbers, like:
# DEB_HG_PYTHON_VERSIONS="3.8" make deb

# /usr/lib/mercurial/hg.

# installations, just the ones that would be installed by `python3-all`. This
# includes the `-i` flag, which claims it's to list all "installed" versions,
