clover: Check if the detected clang libraries are usable
clang-cpp.so is broken in LLVM-9 and doesn't exist in LLVM<9,
however meson will find and try to use system libraries in these cases.
v2: Use helper variable to dedpulicate test code
Move second test inside the condition to avoid testing good clang-cpp twice
v3: Check for cross compilation
v4: style fixes
Fixes: ff1a3a00cb37d84ab9a563f0aa241714876f56b4
