switch to classic bpf macros

Note: this switches
  com_android_networkstack_tethering_util_setupIcmpFilter
over to relative cbpf which in turn is called from:
  com_android_networkstack_tethering_util_setupNaSocket
  com_android_networkstack_tethering_util_setupNsSocket
and tested by p/m/C's:
  TetheringUtilsTest.java - testIcmpSocketFilters()

Test: TreeHugger, atest TetheringUtilsTest
