Commit 8355eb6e11 ("meson: Check if files returned by git ls-files
actually exist") checks the paths printed by git ls-files, which are
relative to the project root, with fs.exists(), which resolves them
relative to the test/fuzz subdirectory. As a result, every corpus
sample was silently skipped, and only the generated directives tests
were registered. Resolve the paths against the project source root
instead.
