    kernel: bpf-headers: fix build error when testing kernel is used
    
    Now that we have separate files for each kernel version,
    only the version/hash for the target kernel are available.
    This cause a missing hash error (and wrong kernel version) for
    bpf-headers when a testing kernel version is used for the current target.
    
    Fix this error by manually including the kernel version/hash file for the
    specific kernel version requested.
