Improve Python install path detection #601

Open roehling opened 8 months ago

This PR makes the customized Python path scheme logic in colcon contingent on an install prefix other than /usr.

This makes colcon more distribution-friendly and prevents the accidental overwriting of system packages in case someone decides to install their packages to /usr. There is no other change in behavior.
