    kernel-module-split.bbclass: add a prefix for module package name pattern
    
    When splitting kernel modules into individual packages, such packages take
    their names from the module name. This is OK under most of the circumstances.
    However, it may lead to package naming collisions if there exists two
    modules with the same name.
    
    Situations like this can occur when building testing modules. For instance,
    there exists testing versions of the modules for non-volatile memory that
    are built with different linker options but bear the same module name. If
    one wants to package such modules, it is be good to be able to name
    packages differently. This can be done by prefixing the package name with
    a KERNEL_MODULE_PACKAGE_PREFIX that can be set by the recipes that inherit
    from module.bbclass.
