socket: use accept4/paccept for nonblocking socket
This reduces the no. of syscalls on Linux systems from 2, accept(2) and
fcntl(2) for setting O_NONBLOCK, to a single accept4(2). On NetBSD, we
have paccept(2) that does the same, if we leave signal masking aside.
Added sys_accept which accepts an extra flags argument than accept(2).
This would opportunistically use accept4/paccept as available. It would
fallback to accept(2) and fcntl(2) otherwise.
While at this, the patch sets FD_CLOEXEC flag on the accepted socket fd.
