Tobias Klauser a50acf3fe0 unix: fix IoctlFileDedupeRange test 
The test introduced in CL 284352 breaks on several builders, either
with IoctlFileDedupeRange returning ENOTTY (as already seen for android
in the TryBot run) or returning EINVAL in the FileDedupeRange.Status
field. Both seem to indicate that the underlying filesystem doesn't
support deduplication, so skip the test in these cases.

Also rename the test to indicate the func it is testing.

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.

away from direct syscalls to libSystem wrappers. Let's not force users
of this package on when they want to do that and re-add the
zsysnum_darwin_*.go files and mark the consts as deprecated.

We can still remove these once macOS actively prevents use of direct
syscalls.
