Fix for #22818: blender doesn't find a systemwide installed python.

What happens is that blender looks for a directory "python" in the same
place as the executable for local installations, but that also means when
you have /usr/bin/blender it will look for /usr/bin/python, which is an
executable. Now it checks if it is actually a directory and not a file.
