cmake: Remove setting CMAKE_FIND_ROOT_PATH_MODE_* variables

These variables affect how CMake locates programs, libraries, include
files, and CMake packages. But the defaults are sufficient for Zephyr.

NEVER: Only host system's root will be searched.
ONLY: Only the paths specified by a variable will be searched. Typically
      these paths point to cross-compilers.
