CMake/macOS: Remove _LIBPATH, avoid link_directories.
After tests were bundled in a single executable and cycles and libmv
created their own tests, the warnings on macOS have gone over 800.
The reason is setting `*_LIBRARIES` to names of the libraries
and later using `link_directories` to link them properly.

Warnings like the following popup for every target/executable,
for every library it links to.
```
ld: warning: directory not found for option
'-L/Users/me/blender-build/blender/../lib/darwin/jpeg/lib/Debug'
```
The patch completes a step towards removing `link_directories` as
mentioned in TODO at several places.
The patch uses absolute paths to link libraries and removes
all `*_LIBPATH`s except `PYTHON_LIBPATH` from
`platform_apple.cmake` file. (The corner case where it's used seems
like dead code. Python is no longer shipped with that file structure.)
Also, unused code for LLVM-3.4 has been removed.
Also, guards to avoid searching libraries in system directories have
been added.
`APPLE` platform now no longer needs `setup_libdirs`,
`cycles_link_directories`, and `link_directories`.
The number of warnings now is less than 100, most of them being
deprecation ones in dependencies.
This patch depended on {rBb746179d0add}, {rB2fdbe4d05011},
{rB402a4cadba49} and {rBd7f482f88ecb}.
