Drop dependency of unittest2; use stdlib unittest instead

Now that Python 2.6 support has been dropped (commit
b67fe8a6f55ba321b602740fdf0bf0d15f074f4f), can simply use Python
unittest. No unique features of unittest2 were in use that aren't also
available in the stdlib unittest. One less dependency.
