sched.h: reduce namespace conflicts in _GNU_SOURCE profile

we have the cpuset macros call calloc/free/memset/memcmp directly so
that they don't depend on any further ABI surface. this is not
namespace-clean, but only affects the _GNU_SOURCE feature profile,
which is not intended to be namespace-clean. nonetheless, reports come
up now and then of things which are gratuitously broken, usually when
an application has wrapped malloc with macros.

this patch parenthesizes the function names so that function-like
macros will not be expanded, and removes the unused declaration of
memcpy. this is not a complete solution, but it should improve things
for affected applications, particularly ones which are not even trying
to use the cpuset interfaces which got them just because g++ always
defines _GNU_SOURCE.
