Clarify that plistlib's load and dump functions take a binary file object (GH-9825)

Browse Source 
The documentation says that the fp parameter to plistlib.load "should be a
readable and binary file object" but the docstring only mentions that it
should be readable. Similarly, plistlib.dump's docstring only mentions
"writable". This commit clarifies that fp should also be binary.
