add test for /system/etc/bpf/{netd,clatd}.o using correct struct sizes

This test is required to ensure that the system is compatible
with future updates of the tethering mainline module, which
updates BPF .o files on device.

This test must already be passing on OEM devices because otherwise
the offload.o program in the Tethering mainline module would bootloop
the device.
