[amdgpu-arch] Fix rpath to run from build dir

Prior to this, amdgpu-arch has RUNPATH set to $ORIGIN/../lib which works
for some installs, but not from the build directory where clang executes
the tool from when running tests.

This cmake option adds the location of the rocr runtime to the RUNPATH
(note, it amends RUNPATH here, despite the cmake option referring to RPATH)
to create a binary that runs from build or install location.

Before:
RUNPATH [$ORIGIN/../lib]
After:
RUNPATH [$ORIGIN/../lib:$HOME/llvm-install/lib]

Credit to Greg for knowing this trick and pointing to examples of it in use
for the aomp build scripts.
