    build: Remove config.h template file
    
    The `config.h` can be generated without any template.
    
    This patch removes the template file and modifies the build file
    to not make any use of it.
    
    It also removes the variable which holds the generated configuration
    file target, as it will not be necessary for any packages building
    libgnome-volume-control.
