Issue #15184: Some config variables in test_sysconfig_module

Browse source 
may differ between sysconfig and distutils.sysconfig due to
compiler customizations on OS X.  For now, move those vars
into a separate test and skip if the customization has taken
place in distutils.  The long-term solution is to eliminate
having two sysconfig modules.

# the Distutils version of sysconfig is used for extension module
# builds, which happens earlier in the Distutils tests. This may
# cause the following tests to fail since no tests have caused
# the global version of sysconfig to call the customization yet.
# The solution for now is to simply skip this test in this case.
# The longer-term solution is to only have one version of sysconfig.
