Bug #192341 - Make emerge bail out on FreeBSD if the freebsd python module

fails to import. Display a notification that "ignore-missing-freebsd-module"
can be added to FEATURES in order to bypass the error. If that feature is
enabled but the freebsd python module imported successfully, show a warning
message since the user should remove if from FEATURES asap.
