#15685 made peer_test.go more portable by using random free port instead of hardcoded port 30303 (#15687)

Improves test portability by resolving 127.0.0.1:0
to get a random free port instead of the hard coded one. Now
the test works if you have a running node on the same
interface already.

Fixes #15685
