Subject: [PATCH] remove sys/sysctl.h

With musl irrlicht doesn't build due to missing sys/sysctl.h

fatal error: sys/sysctl.h: No such file or directory

From [1]
"sysctl does not work, and NEVER worked. using it is bogus.
it was a bogus experimental syscall that was deprecated before
it was ever used (basically, a broken binary version of
/proc/sys, without any stability between kernel versions for
what the binary constants meant)."
