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.

# By default, use our own standalone_fuzz_target_runner.
# This runner does no fuzzing, but simply executes the inputs
# provided via parameters.
# Run e.g. "make all LIB_FUZZING_ENGINE=/path/to/libFuzzer.a"
# to link the fuzzer(s) against a real fuzzing engine.
#
# OSS-Fuzz will define its own value for LIB_FUZZING_ENGINE.
