Andre Fredette f5d4fdedba Exercise all new TCX APIs in the TCX integration test
Also removed unused code in the tcx eBPF program.

I've manually verified that all the programs get attached in the correct
order.

TODO: Add code to the integration test to automatically verify that the
programs are attached in the correct order after the API based on the
BPF_PROG_QUERY syscall has been implemented.
