serge-sans-paille efc472b57d Bug 1886479 - Introduce the possibility to provide a fallback in python site r=mach-reviewers,ahal ...

pyyaml is already vendored but as a consequence we don't benefit from
the faster native loader.

Introduce the possibility to provide a vendored package as fallback to
an optional pypi package. If the pypi package install fails, we can
still use the vendored one without the speed benefit.

This makes my `mach build export` step 8% faster.
