    build: fix dependency of kernel_menuconfig target
    
    When running "make kernel_menuconfig" in a clean tree, it fails with:
    
        make[1]: *** No rule to make target 'tools/quilt/install'.  Stop.
    
    Replacing the dependency with 'tools/quilt/compile' fixes the issue (quilt
    and all its prerequisites will be built, and quilt will be installed in
    staging_dir).
