wireguard: allowedips: initialize list head in selftest

commit 46cfe8eee285cde465b420637507884551f5d7ca upstream.

The randomized trie tests weren't initializing the dummy peer list head,
resulting in a NULL pointer dereference when used. Fix this by
initializing it in the randomized trie test, just like we do for the
static unit test.

While we're at it, all of the other strings like this have the word
"self-test", so add it to the missing place here.
