net-wireless/rtl8821cu: fix multiple issues, please read details

If you overwrite src_prepare, be sure to call default or eapply_user
emerge will fail if it is missing.

Patches can also go in the patches variable

All the functions here are already added by inheriting the eclass
so there's no need to specify them manually
