Besides probing BPF information in running system, bpftool is also used in generating skeleton, dumping BTF, etc. that is widely used in modern BPF development. Make it available as a host tool so that we can use it in package build. Tested build targeting malta/le on Arch Linux x86_64. bpftools currently does not support processing cross-endian BPF objects, so big-endian host is needed to build for big-endian targets using bpftools.
