DragonFly build system: set KERNCONF environment variable by default

autokernconf_profile.patch

commit 318bc983b7cb89a6a7058690ea7b76eb1e89f26b

    set KERNCONF environment variable by default
    
    to the currently running kernel's config name (uname -i).
    
    A straightforward kernel upgrade thus reduces to
    
    make buildkernel
    make installkernel
    
    Note that if KERNCONFDIR was set before it must be set now as well.
