Add kernel livepatch-devel package
    
    Resolving non-exported static symbols in kernel livepatches cannot
    be done implicitly. For such, the relocations of these symbols must
    follow a specially crafted format in the respective elf file. Willing
    to make the task of converting the elf into the right format, a tool
    named klp-convert was proposed. Through a file that maps all kernel
    symbols into their respective kernel object, this tool infers which
    non-exported symbol is relative to a livepatch relocation and
    automatically formats the final elf file.
    
    Add support to the generation of a map file right after the kernel
    compilation.
    
    Add the package kernel-<flavour>-livepatch-devel that brings
    the map file.
