Add a selftest to verify bonding behavior when `lacp_active` is set to `off`.

The test checks the following:
- The passive LACP bond should not send LACPDUs before receiving a partner's
  LACPDU.
- The transmitted LACPDUs must not include the active flag.
- After transitioning to EXPIRED and DEFAULTED states, the passive side should
  still not initiate LACPDUs.

Strangely this test fails on a normal kernel build but passes with
debug options enabled:

I guess on the normal kernel, the checking starts too soon before negotiation
finished. I will add some sleep time before checking.
