    kernel: predefine KBUILD_BUILD_USER and KBUILD_BUILD_HOST
    
    By exporting KBUILD_BUILD_USER with a pre-defined value we improve the
    reproducibility of the kernel and remove the requirement for whoami in the
    HOSTTOOLS.
    KBUILD_BUILD_HOST also helps improve the reproducibility of the kernel.
    
    For more kernel reproducibility options see:
