test_networking: use appropriate assert helpers

test_networking: use appropriate assert helpers

In all unit tests we rely on CMocka's provided assert helpers.

However, test_networking.c was still on the default assert() call,
which we try to avoid in favour of more appropriate helpers.

Substitute them all with assert_*() from CMocka.
