libbpf: Add bpf_object__unpin()
For bpf_object__pin_programs() there is bpf_object__unpin_programs().
Likewise bpf_object__unpin_maps() for bpf_object__pin_maps().
But no bpf_object__unpin() for bpf_object__pin(). Adding the former adds
symmetry to the API.
It's also convenient for cleanup in application code. It's an API I
would've used if it was available for a repro I was writing earlier.
