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. Signed-off-by: Peter Morrow <[email protected]> Signed-off-by: Khem Raj <[email protected]>
