[libgdata: 1/6] build: Define G_LOG_DOMAIN in c_args rather than config.h

    build: Define G_LOG_DOMAIN in c_args rather than config.h
    
    Defining it in `config.h` means that *every* C file which emits a log or
    debug message needs to remember to include `config.h`. It’s a lot
    simpler and less error-prone to define `G_LOG_DOMAIN` in the `c_args`
    instead.
