re-order normalizations in run-make linker-warning test

otherwise a buildroot containing `libpanic_abort` would be mangled before being
replaced by the build root placeholder value..

e.g., running `./x.py test --verbose tests/run-make/linker-warning` with rustc
checked out in ~/ext/rustc-libpanic_abort will result in (output slightly shortened):

```
