Currently we export SOCK_NONBLOCK to user space but that conflicts
with the definition from glibc leading to compilation errors in user
programs (e.g. see Debian bug #658460).  The generic socket.h
restricts the definition of SOCK_NONBLOCK to the kernel, as does
the MIPS specific socket.h, so let's do the same on Alpha.
