Modify call_bad_names test to use regex and add to blacklist

This modifies the test performed in call_bad_names to use re.match, adds
additional functions to the blacklist, and adds examples that trigger those
new blacklist entries.

It is an intial pass at addressing https://github.com/chair6/bandit/issues/6,
but further changes will be required to clean this up, including separating
configuration from test code.
