The sanitizer build paths passed multi-word flags as an unquoted string, so
the cmake invocation word-split "-fsanitize=address,undefined
-fno-omit-frame-pointer" and handed -fno-omit-frame-pointer to cmake as a
bare unknown argument ("CMake Error: Unknown argument"). Switch to a bash
array so each -DCMAKE_*_FLAGS value stays a single argument. Unblocks
rebuilding the instrumented __lib_debug libraries the fuzz build links.
