Gobview tries to load source files via the same path that Goblint had, but this doesn't work because the path relative to CWD during Goblint run isn't relatively the same to the save_run directory.

Maybe the source files should just be copied into save_run as well, like how g2html does it? Because adjusting the relative paths wouldn't still work, if the analyzed source files are not inside the directory served by the web server.
