LOG: [runtimes] Add explicit offload arch tool dependencies (#206076)

Needed for the offload unittests which detect the target arch at
configure time if not forced by OFFLOAD_TESTS_FORCE_AMDGPU_ARCH. Bug had
been masked by the dependency on flang, which we recently removed in
https://github.com/llvm/llvm-project/pull/198205.

Claude assisted with this patch.
