Use git_common to call git

Browse Source 
In preparation for some Windows optimizations to how git_common calls
git it is important to use git_common more widely, specifically from
scm.py and gclient_scm.py. This change updates scm.py and gclient_scm.py
and updates the associated tests:

Test command lines used when updating the tests include:
vpython3 tests/gclient_scm_test.py ManagedGitWrapperTestCaseMock.testUpdateConflict

vpython3 tests/gclient_scm_test.py GerritChangesTest.testRecoversAfterPatchFailure

vpython3 tests/gerrit_util_test.py CookiesAuthenticatorTest.testGetGitcookiesPath
