scons: Exclude parsetab.py when collecting python deps.

Browse Source 
Because we don't have a good way to actually figure out what python
files we depend on, we have to use Glob and wildcard matching to depend
on all potential python files. Unfortunately that will pick up the
parsetab.py file that ply generates, which is a cached intermediate file
and not an input.
