[Offload] Fix per-target install directory (#89645)

Summary:
The move from `openmp` to `offload` did not preserve the per-target
runtime directory installation. This is important because this
per-target directory is always included first and is likely the de-facto
way to handle these going forward. Without this installation, old
installations of the library will be linked against first.
