[RFC PATCH net-next 06/10] selftests: forwarding: Add net/lib.sh to TEST_INCLUDES

[Benjamin Poirier <bpoirier@nvidia.com>]

Since commit 25ae948b4478 ("selftests/net: add lib.sh"), when exporting the
forwarding tests and running them, the tests that import
net/forwarding/lib.sh fail to import net/lib.sh. This is especially a
problem for the tests that use functions from net/lib.sh, like pedit_ip.sh:

$ make install TARGETS="drivers/net/forwarding"
$ cd kselftest_install/net/forwarding
$ ./pedit_ip.sh veth{0..3}
lib.sh: line 38: /src/linux/tools/testing/selftests/kselftest_install/net/forwarding/../lib.sh: No such file or directory
TEST: ping                                                          [ OK ]
TEST: ping6                                                         [ OK ]
./pedit_ip.sh: line 135: busywait: command not found

        Expected to get 10 packets, but got .
./pedit_ip.sh: line 135: busywait: command not found

In order for net/lib.sh to be exported along with forwarding tests, add
net/lib.sh to TEST_INCLUDES. This is the result after this commit:

$ ./pedit_ip.sh veth{0..3}
TEST: ping                                                          [ OK ]
TEST: ping6                                                         [ OK ]
TEST: dev veth1 ingress pedit ip src set 198.51.100.1               [ OK ]
TEST: dev veth2 egress pedit ip src set 198.51.100.1                [ OK ]
TEST: dev veth1 ingress pedit ip dst set 198.51.100.1               [ OK ]
TEST: dev veth2 egress pedit ip dst set 198.51.100.1                [ OK ]
TEST: dev veth1 ingress pedit ip6 src set 2001:db8:2::1             [ OK ]
TEST: dev veth2 egress pedit ip6 src set 2001:db8:2::1              [ OK ]
TEST: dev veth1 ingress pedit ip6 dst set 2001:db8:2::1             [ OK ]
TEST: dev veth2 egress pedit ip6 dst set 2001:db8:2::1              [ OK ]
