Subject: [PATCH] Fix build failure on musl

Build fails on:
/home/test/autobuild/run/instance-0/output/build/chipmunk-7.0.2/src/cpHastySpace.c:11:24: fatal error: sys/sysctl.h: No such file or directory

Indeed, sys/sysctl.h is not available on musl so include this header
only if __APPLE__ is defined as sysctlbyname is only used in this case.

Fixes:
