Do not drop all wheels with venv_rebuild

Removal of venv_build_host_wheel_path leads to all wheels for all
services being dropped which results in other role brokeness
since we build wheels only when requirements or constraints
file is changed. Also we technically don't need to clean it up, since
removal of just rest of the files will lead to wheels being rebuild.

This change should make usage venv_rebuild safe and not breaking wheels
for all services rather then single one.
