Deprecation Warning time.clock()

[claudio]

There is a call to time.clock in Crypto/Random/_UserFriendlyRNG.py:77:
it causes the following warning, in the future may become a problem:
DeprecationWarning: time.clock has been deprecated in Python 3.3 and will be removed from Python 3.8: use time.perf_counter or time.process_time instead
  t = time.clock()

[Al Smith (ajs1k)]

This is now busted as time.clock() has been removed from python3.8.

s/time.clock/time.process_time/ and all is good again.

[Al Smith (ajs1k)]

Or perhaps this:

if 'process_time' in dir(time):
    t = time.process_time()
else:
    t = time.clock()
