ci: test real dependency installation for pip
In the past, the pip smoke test inhibited actual dependency
installation, but that fails in different environments for setuptools
itself. Since it isn't what we actually want to test (which is pip
install), allow this to call home, if HGTESTS_ALLOW_NETIO=1 is set
in the environment.
