kernel: params/rcutiny needs module.h not moduleparam.h

Through various other twisted include paths, these files were
getting the full module.h file, and hence living the illusion
that it really only needed moduleparam.h -- but the reality
is that once you remove module.h, you will get screenfulls of
things like:

kernel/params.c:583: warning: ‘struct module_kobject’ declared inside parameter list

The file really requires module.h so simply make it so.  As the
file module.h grabs moduleparam.h on the fly, all will be well.
