tools/setup-virtualenv: do not use wheel if wheelhouse does not exist

some times, developer does not use install-deps.sh to prepare the wheel
at all. in that case, just do not pass the wheelhouse options to pip.

this helps to silence the pip warnings complaining that the wheelhouse does
not exist.
