Strip down fmacros.h

strerror_r and addrinfo require _POSIX_C_SOURCE >= 200112L,  which is
implied by _XOPEN_SOURCE >= 600. With the removal of AF_LOCAL usage,
the only non-standard features being used are the TCP_KEEP* socket
flags. _DARWIN_C_SOURCE is required to expose TCP_KEEPALIVE.

Fall back to using _XOPEN_SOURCE 600 for all platforms, and
additionally define _DARWIN_C_SOURCE for Darwin.
