Simon McVittie 76a7b629bf test: Add some common code to load test resources
As well as reducing duplication, this lets the tests load their resources
from the SDL_GetBasePath() on platforms that support it, which is useful
if the tests are compiled along with the rest of SDL and installed below
/usr as manual tests, similar to GNOME's installed-tests convention.

Thanks to Ozkan Sezer for the OS/2 build glue.
