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.

My original bpftools package made "variant" builds of bpftool and libbpf
as a convenience, since both used the same local kernel sources with the
same versioning. This is no longer the case, since the commit below
switched to using an out-of-tree build mirror hosting repos for each.
Replace bpftools with separate bpftool and libbpf packages, each simplified
and correctly versioned. Also fix the broken libbpf ABI introduced in the
same commit. Existing build .config files are not impacted.
Fixes: 00cbf6f6ab ("bpftools: update to standalone bpftools + libbpf, use the latest version")
