bpo-35513: Replace time.time() with time.monotonic() in tests (GH-11182)


Replace time.time() with time.monotonic() in tests to measure time
delta.

test_zipfile64: display progress every minute (60 secs) rather than
every 5 minutes (5*60 seconds).
(cherry picked from commit 2cf4c202ffeb30787c944365ba54013688b854c2)
