[PR #3345] fix more PY3.8 fails

File closes in msvs tool
Context manager in rpm tool
Dummy compiler, assembler scripts can be called in unexpected
  ways (namely by gcc tool init), which passes --version flag.
  don't take exception on the getopt call.
Try again to undo my breakage of _subproc, which was failing on Win+PY27
