Test suite fails to run when not using virtualenv

[Johannes Erdfelt]

A recent change (it appears to be 0b28e574afa8563524e21d31d95972c8ba126de2) has caused the test suite to silently fail to run when not using a virtualenv.

% ./run_tests.sh -N
%

It appears to be a python path problem since setting PYTHONPATH to the top of the tree allows the test suite to run.

% PYTHONPATH=$PWD ./run_tests.sh -N
[lots of test suite output]
