[cmake] [libunwind] Fix find_path() problems when cross compiling
When CMAKE_SYSROOT or CMAKE_FIND_ROOT_PATH is set, cmake
recommends setting CMAKE_FIND_ROOT_PATH_MODE_INCLUDE=ONLY
globally which means find_path() always prepends CMAKE_SYSROOT or
CMAKE_FIND_ROOT_PATH to all paths used in the search.
However, this find_path() invocation is looking for a path in the
libcxx project on the host system, not the target system,
which can be done by passing NO_CMAKE_FIND_ROOT_PATH.
