sys-devel/clang: Fix unused LLVM_EXPERIMENTAL... warning

Revert back to using LLVM_TARGETS_TO_BUILD since
LLVM_EXPERIMENTAL_TARGETS_TO_BUILD logic is not implemented in clang
(or the installed LLVM CMake files). However, the target check is not
implemented either, so we can just push the experimental targets into
the regular variable.
