+-- Make the Python wheel build/install robust against platform tag mismatches.

+-- differ from what SCons reconstructs (for example, host/jail OSVERSION
+-- differences in Poudriere). Instead of hardcoding the expected wheel filename,
+-- build a sentinel file and discover the actual .whl when installing.
