CMakeLists.txt: define DEBUG=1 only when CMAKE_BUILD_TYPE=Debug

When building with CMAKE_BUILD_TYPE=RelWithDebInfo the development debug
code should not be enabled, so don't define DEBUG=1 in DEBUG_FLAGS as
this will end up being both in CMAKE_C_FLAGS_DEBUG and
CMAKE_C_FLAGS_RELWITHDEBINFO.

Instead define DEBUG=1 only for CMAKE_C_FLAGS_DEBUG so it gets used only
when CMAKE_BUILD_TYPE=Debug.
