BUG: tests fail x86 due to direct wired socket syscalls on Linux 4.3

This appears due to changes in Linux 4.3 which enabled direct access to the socket syscalls, see Andy's commit:

x86/entry/syscalls: Wire up 32-bit direct socket calls

On x86_64, there's no socketcall syscall; instead all of the
socket calls are real syscalls.  For 32-bit programs, we're
stuck offering the socketcall syscall, but it would be nice to
expose the direct calls as well.  This will enable seccomp to
filter socket calls (for new userspace only, but that's fine for
some applications) and it will provide a tiny performance boost.
