Kludge cryptech_backup into working with Python 3.8
PyCrypto is past EOL and we really should move on, but not this close to a release. Working around the deprecated time.clock function is sick but appears to be harmless given the way that function is used in PyCrypto's internal RNG. Would be better just to use os.urandom() but that would be a much larger change. In theory, PyCryptodome is a drop-in replacement for PyCrypto which would solve this problem for us. Unfortunately, it's much less of a drop-in than its documentation suggests, even before one gets into Debian and pip disagreeing on what its name should be. Maybe someday, but not today.
