Subject: [PATCH] 00132-add-rpmbuild-hooks-to-unittest.patch

Add non-standard hooks to unittest for use in the "check" phase below, when
running selftests within the build:
  @unittest._skipInRpmBuild(reason)
for tests that hang or fail intermittently within the build environment, and:
  @unittest._expectedFailureInRpmBuild
for tests that always fail within the build environment

The hooks only take effect if WITHIN_PYTHON_RPM_BUILD is set in the
environment, which we set manually in the appropriate portion of the "check"
phase below (and which potentially other python-* rpms could set, to reuse
these unittest hooks in their own "check" phases)
