Exclude _testclinic_depr.c.h from c-analyzer (GH-137086)

_testclinic.c mocks out PY_VERSION_HEX to 3.8 before including
_testclinic_depr.c.h to avoid the errors the preprocessor would
otherwise throw due to the deprecation feature it is testing.

Also partially revert 74e2acd:
this restores Modules/_testclinic.c to match the same file in the 3.14
branch.
