Remove global CMAKE_INSTALL_RPATH_USE_LINK_PATH directive (#37737)
Summary:
Closes gh-35418,
PR gh-16414 added [the `CMAKE_INSTALL_RPATH_USE_LINK_PATH`directive](https://github.com/pytorch/pytorch/pull/16414/files#diff-dcf5891602b4162c36c2125c806639c5R16) which is non-standard and will cause CMake to write an `RPATH` entry for libraries outside the current build. Removing it leaves an RPATH entry for `$ORIGIN` but removes the entries for things like `/usr/local/cuda-10.2/lib64/stubs:/usr/local/cuda-10.2/lib64` for `libcaffe2_nvrtc.so` on linux.
The added test fails before this PR, passes after. It is equivalent to checking `objdump -p torch/lib/libcaffe2_nvrtc.so | grep RPATH` for an external path to the directory where cuda "lives"
I am not sure if it solve the `rpath/libc++.1.dylib` problem for `_C.cpython-37m-darwin.so` on macOS in issue gh-36941
