  [HIP] Fix version detection for old HIP-PATH

ROCm used to install components under individual directories,
e.g. HIP installed to /opt/rocm/hip and rocblas installed to
/opt/rocm/rocblas. ROCm has transitioned to a flat directory
structure where all components are installed to /opt/rocm.
HIP-PATH and --hip-path are supposed to be /opt/rocm as
clang detect HIP version by /opt/rocm/share/hip/version.
However, some existing HIP app still uses HIP-PATH=/opt/rocm/hip.
To avoid regression, clang will also try detect share/hip/version
under the parent directory of HIP-PATH or --hip-path.
This way, the detection will work for both new HIP-PATH and
old HIP-PATH.
