Subject: waf: Replace python installation rule to allow PYTHONARCHDIR and
 PYTHONDIR

The old rule could only substitute one part of one line, but we need
to add a second line to handle when PYTHONDIR and PYTHONARCHDIR do not
match.

This also avoids shelling out to sed with a regex, which was difficult
to read.
