Subject: [PATCH] Look for Python3 again in `SearchInstalledSoftware.cmake`

This commit essentially reverts a288ff9 from four years ago, which was
also part of the multi-python machinery that is not necessary anymore
after Python 2 support was dropped.

Also, make the choice of looked-up components consistent with what is
actually required.
