tc-testing: use a plugin to build eBPF program

use a TDC plugin, instead of building eBPF programs in the 'setup' stage.
'-B' argument can be used to build eBPF programs in $EBPFDIR directory,
in the 'pre-suite' stage. Binaries are then cleaned in 'post-suite' stage.

and the other is a test whether the command leaked memory or not.
(This one is a preliminary version, it may not work quite right yet,
but the overall template is there and it should only need tweaks.)
- buildebpfPlugin.py:
builds all programs in $EBPFDIR.
