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.
