Revert "python-generic: set meta.broken for disabled packages instead of raising an error during evaluation"

This reverts commit 79a5fec9.

meta.broken uses 'throw' under the hood so it can not improve the
current situation. Reverting to previous behaviour gives us correct
error message to the user indicating that interpreter is not supported.

Correcting Hydra output is out of scope of Python packaging.
