package/network-manager: add patch to set mobile-broadband-provider-info-database location

When building network-manager in cross-compile environment pkg-config returns
the wrong path to the mobile-broadband-provider-info database.

By adding the option 'mobile_broadband_provider_info_database' to set the
correct path to the datafile this can be solved.
