NetBSD: Make _cpuset an extern type

tgross35 · tgross35 · commit ac8cd4177b33 · 2025-11-04T03:38:31.000-06:00
Our definition was correct for how it is defined internally, but in the header where it is included it is an incomplete definition. Link: https://github.com/NetBSD/src/blob/6017cb90fd7d83ed6e45d93129b12d525978c2fa/sys/sys/sched.h#L99 (backport <#4782>) (cherry picked from commit 95e5cdb)
