[tor-commits] [tor/master] prop250: Fix unit tests about the RSA fingerprint check
commit d43646e191dec6f800f63acb6a6861190b77d86f

prop250: Fix unit tests about the RSA fingerprint check
Code has been changed so every RSA fingerprint for a commit in our state is
validated before being used. This fixes the unit tests by mocking one of the
key function and updating the hardcoded state string.
Also, fix a time parsing overflow on platforms with 32bit time_t
