[libc] Remove some sched.h includes (llvm#151425)

boomanaiden154 · krishna2803 · commit 27cc35b3b13d · 2025-08-12T18:05:38.000+05:30
This patch removes some sched.h includes, preferring the proxy headers.
This patch does not clean them all up as some proxy type headers need to
be added, like for `struct sched_param`.
