Issue pypa#2677: Disable wheels for setup.py options.

Using --install-options, --build-options, --global-options changes
the way that setup.py behaves, and isn't honoured by the wheel code.
The new wheel autobuilding code made this very obvious - disable
the use of wheels when these options are supplied.
