bpo-37421: urllib.request tests call urlcleanup() (GH-14529)

urllib.request tests now call urlcleanup() to remove temporary files
created by urlretrieve() tests and to clear the _opener global
variable set by urlopen() and functions calling indirectly urlopen().

regrtest now checks if urllib.request._url_tempfiles and
urllib.request._opener are changed by tests.
