net/sched: Remove alias of sch_clsact

The module sch_ingress stands out among net/sched modules
because it provides multiple act/sch functionalities in a single .ko.
They have aliases to make autoloading work for any of the provided
functionalities.

Since the autoloading was changed to uniformly request any functionality
under its alias, the non-systemic aliases can be removed now (i.e.
assuming the alias were only used to ensure autoloading).
