ci: deal better with hanging tests

Exactly like we just did with the `win test` jobs, let's establish
timeouts for the other jobs that run Git's test suite (giving the ASAN
and macOS jobs 60 minutes, all other jobs 20 minutes to finish, which is
generous), and detect timed-out tests and handle them the same as failed
ones.
