net/sched: Add helper macros with module names

The macros are preparation for adding module aliases en mass in a
separate commit.
Although it would be tempting to create aliases like cls-foo for name
cls_foo, this could not be used because modprobe utilities treat '-' and
'_' interchangeably.
In the end, the naming follows pattern of proto modules in linux/net.h.
