[PATCH net-next 08/14] selftests: lib: Define more kselftest exit codes

[Petr Machata <petrm@nvidia.com>]

The following patches will operate with more exit codes besides
ksft_skip. Add them here.

Additionally, move a duplicated skip exit code definition from
forwarding/tc_tunnel_key.sh. Keep a similar duplicate in
forwarding/devlink_lib.sh, because even though lib.sh will have
been sourced in all cases where devlink_lib is, the inclusion is not
visible in the file itself, and relying on it would be confusing.
