Add detection for kernel version, and adapt the BPF program based on
kernel support. This way, users will get the best possible performance
from the BPF program.

Please do explicit feature detection instead of relying on the kernel
version number; some distro kernels are known to have a creative notion
of their own version, which is not really related to the features they
actually support (I'm sure you know which one I'm referring to ;)).
