When compiles program with `-C rpath=yes` but with no output filename specified, or with filename ONLY, we will get an ICE for now. Fix it by treat empty `output` path in `get_rpath_relative_to_output` as current dir.
Before this patch:
```bash
rustc -C prefer_dynamic=yes -C rpath=yes -O h.rs # ICE, no output filename specified
rustc -o hello -C prefer_dynamic=yes -C rpath=yes -O h.rs # ICE, output filename has no path
rustc -o ./hello -C prefer_dynamic=yes -C rpath=yes -O h.rs # Works
```
All those examples work after the patch.
Close #119571.
Close #125785.
