bsd-user/arm/target_arch_cpu.h: Only support FreeBSD sys calls

Browse Source 
Since we don't build on OpenBSD, only do FreeBSD system calls here. In
the future, we'll need to move this to some place like
bsd-user/freebsd/arm/mumble.h, but until then just leave this
inline. This reflects changes to the upstream.
