libkern: tidy up memset

1. Remove special-casing of 0 as it just results in an extra function call.
This is clearly pessimal.
2. Drop the inline stuff. For the most part it is much better served with
__builtin_memset (coming later).
3. Move the declaration to systm.h to match other funcs.

Archs are encouraged to implement the variant for their own platform so that
this implementation can be dropped.
