runner: Strada baselines rarely put `./` on front of filename, but Corsa always removes it

Corsa calls getNormalisedAbsolutePath in the compiler runner instead of waiting for the Program to do it. I think this is the right thing, but means that paths with . and .. will differ from Strada baselines.

This should be pretty easy to fix up in a compatibility run of Strada baselines.
