bundle-linux.sh: match ldd's absolute paths in the SDL2 check (CI red fix)

The $ORIGIN verification compared ldd's absolute resolved path against the
relative $OUT, so it always failed even though the bundled libSDL2 was the
copy being resolved (CI 34778363397 showed exactly that). Match both forms;
the remaining-deps listing now filters by bundle dir name for the same
reason.
