PYCC tests failing due to missing setuptools

[sklam]

Latent test failures due to missing setuptools revealed in "vanilla" config: https://dev.azure.com/numba/numba/_build/results?buildId=14917&view=logs&j=bda6963e-59cd-52f6-042b-2835f24868f2&t=c5723dd8-2190-5808-bf7a-548c716a08a4.
Failures occur when the tests are selected by gitdiff.

#8915 updates the module numba.tests.test_deprecations which contains the failing tests noted in the OP. The gitdiff testing spots the update and runs that module, in the "vanilla" configuration the log contains:

2023-04-25T09:06:37.9332791Z test_pycc_CC (numba.tests.test_deprecations.TestDeprecation) ... skipped 'Test needs setuptools'
2023-04-25T09:06:37.9333533Z test_pycc_module (numba.tests.test_deprecations.TestDeprecation) ... skipped 'Test needs setuptools'

I'm reasonably convinced that has already been fixed by 0d1969a in #8909.
