genetlink: Build a generic netlink family module alias
Generic netlink searches for -type- formatted aliases when requesting a module to fulfill a protocol request (i.e. net-pf-16-proto-16-type-<x>, where x is a type value). However generic netlink protocols have no well defined type numbers, they have string names. Modify genl_ctrl_getfamily to request an alias in the format net-pf-16-proto-16-family-<x> instead, where x is a generic string, and add a macro that builds on the previously added MODULE_ALIAS_NET_PF_PROTO_NAME macro to allow modules to specifify those generic strings. Note, l2tp previously hacked together an net-pf-16-proto-16-type-l2tp alias using the MODULE_ALIAS macro, with these updates we can convert that to use the PROTO_NAME macro.
