Remove libxdp header files not used by any bpf-examples

Browse Source 
When some bpf example use libxdp then these can be re-added, along
with description of why projects needs to include these files.

Files removed:
 headers/xdp/libxdp.h
 headers/xdp/prog_dispatcher.h
 headers/xdp/xdp_helpers.h

Fixes: 4513664ca3 ("Initial import with encap-forward example")
