tests: Fix strict aliasing of sockaddr structures

Casting from one struct sockaddr type to another breaks C’s strict
aliasing rules (variables of different types cannot alias). Fix this
cleanly by using unions of struct sockaddrs to convert between the
types (i.e. type-punning).

I wish sockaddr didn’t have to be this painful.
