Tobias Klauser 8ebf48af03 unix: check gid in TestGetsockoptXucred 
macOS (and the BSDs) report all groups in Xucred, the first one being
the GID.

Also use Socketpair/Close from golang.org/x/sys/unix instead of package
syscall.

Tobias Klauser 760e229fe7 unix: test anyToSockaddr without creating actual socket 
Test_anyToSockaddr on linux needs to create a socket with the given
domain, type and protocol in order to test anyToSockaddr. Depending on
kernel version, permission and other factors, a given combination might
not be available on the system that runs the test, as is e.g. the case
for AF_CAN/SOCK_DGRAM/CAN_J1939 on several builders after CL 272767.

The only reason to create the socket is to be able to get the socket
protocol in anyToSockaddr using GetsockoptInt(..., SO_PROTOCOL). Move
this implementation into a wrapper func which can be overriden in tests
to with a func unconditionally returning the protocol under test. This
makes the test less dependent on the system it runs on and should fix
the builders broken by CL 272767.

While at it also removed the unused SocketSpec type in
syscall_internal_bsd_test.go and remove an unnecessary error var
declaration.
