Make generated selftest output match for in-source builds

When generate_expected_output.py is run for an in-source build, the
raw output contains no paths to the sources for the script to whittle
down, as it does for shadow builds, to just the path from qtbase down.
So kludge together some extra regexes that can fix that up and tweak
some relevant code to provide them with the data they need.
