[issue10290] Fix resource warnings in distutils

[Brian Curtin]

New submission from Brian Curtin <curtin at acm.org>:

The attached patch cleans up the numerous ResourceWarning messages that distutils test runs generate. The changes basically just close all open files - some in the test suite, some in the library code.
No context managers were used since distutils appears in PEP 291 as requiring 2.3 support.
