Most Linux distributions allow installing multiple versions of Python side-by-side, where binaries are installed as `/usr/bin/pythonX.Y` and headers are installed into `/usr/include/pythonX.Y`. On such system PET will look for the first `patchlevel.h` header found in `/usr/include`, which would basically be the first Python version in the directory iteration order. Fix this by only considering versions that match the `MAJOR.MINOR` version found in `pyvenv.cfg` of the environment (if one exists). This is valid, because major Python upgrades almost always require the environment to be re-created.
