bpo-30108: Restore sys.path in test_site (#1197) (#1378)

Browse source 
Add setUpModule() and tearDownModule() functions to test_site to
save/restore sys.path at the module level to prevent warning if the
user site directory is created, since site.addsitedir() modifies
sys.path.
(cherry picked from commit b85c136903)
