kernel-binary: suse-module-tools is also required when installed
    
    Requires(pre) adds dependency for the specific sciptlet.
    
    However, suse-module-tools also ships modprobe.d files which may be
    needed at posttrans time or any time the kernel is on the system for
    generating ramdisk. Add plain Requires as well.
