libbpf: remove kernel configuration dependency
This dependency introduces a cycle with pahole:
```
kernel --> pahole --> libbpf
^ /
\ /
`------------------<
```
pahole is a build time dependency of the kernel which is required to
generate BTF symbols. The dependency on the kernel configuration is nice
to have but makes using pahole during kernel compile time impossible.
Furthermore this dependency doesn't make sense when building libbpf
purely to ship it via a SDK.
