bpf_tethering.h -> offload.h

match header file with bpf program

Locations to change found via:
  https://source.corp.google.com/search?q=p:aosp-master%20(%5E%7C%5B%5E_%5D)bpf_tethering.h

Core reasoning for this will be to match the .h naming
that we'll have for netd.c and clatd.c once we get rid of bpf_shared.h
