e770392084aa52e5568cf001da4d537fda1d71b3 test: addrman: test self-announcement time penalty handling (Bruno Garcia)

Pull request description:

  This PR adds a test case for addrman that verifies that addresses announcing themselves (addr == source) are exempt from time penalties, while addresses announced by others receive the expected penalty.

  It fixes the following mutant (https://corecheck.dev/mutation/src/addrman.cpp#L561):
