Some Mac site-package locations are not treated as library by the debugger

[karthiknadig]

For example, this location is not treated as library by pydevd in Python 3.7:
/Users/vsts/Library/Python/3.7/lib/python/site-packages

NOTE: To reproduce this issue with ptvsd. Remove the line in wrapper.py where we set project root (look for CMD_SET_PROJECT_ROOTS). Then run the pollowing test on Mac python 3.7

python3 -m tests -v tests.system_tests.test_web_frameworks.FlaskLaunchTests.test_with_unhandled_exceptions

For reference, these are the sys.path values from our CI environment:

Strange... in my tests it seems that /Users/vsts/Library/Python/3.7/lib/python/site-packages does appear as a site package for pydevd (although /usr/local/lib/python3.7/site-packages doesn't and I still didn't discover how to get this entry).

Anyways, just giving some info, will investigate further.

[karthiknadig]

Need to verify if this is fixed

[karthiknadig]

Verified.
