[PATCH v9] simple-tc: Fix simple-tc not being active if set

[Adrian Schmutzler]

Fixes: #55

This reintroduces the broken simple-tc.

Changes in v9:
This is an ALTERNATIVE version to the v8 patch. Here,
simple-tc functionality is put into a separate package
fff-simple-tc, so you can select fff-network without
necessarily including the simple-tc functions.
