forkfd: Define __BSD_VISIBLE and _NETBSD_SOURCE. 

pipe2's availability on BSD operating systems depends on the
__BSD_VISIBLE macro on FreeBSD and OpenBSD and _NETBSD_SOURCE on
NetBSD (DragonFly BSD appears to define it unconditionally).

Those two macros are generally set by default, except when
_POSIX_C_SOURCE is set. Since we consciously set _POSIX_C_SOURCE but
need pipe2, explicitly define the visibility macros.

This fixes the -no-pch build on FreeBSD at least.
