package/package_rpm: Disable font_provides configuration for reproducibilty

The host may or may not have fc-cache which is used for find provides
information by rpmdeps. This lead to non-deterministic build output.
Disable the font provides code so we have deterministic builds,
we have nothing using/relying on it at this point.

Need to disable this in both the rpmdeps code and in package_rpm
itself although the latter shouldn't be being used.
