Martin Stein b9141f98af test/black_hole: fix "packet alloc failed"
The Uplink_test used to end in an uncaucht exception about a failed packet
allocation on several x86_32 platforms.

* Destruct and re-construct the corresponding TX packet allocator during a
  link-down-up step in the Uplink test. Fixes the exceptions but results in a
  never ending test.
* Decouple the link-down-up steps from the handling of packet stream signals
  by simply triggering it with a local periodic timeout of 1 sec period.
  This prevents that the Uplink_test never finishes because it destructs the
  Uplink connection too often.
* The test finishes not before at least 3 link-down-up steps were executed.
* Replace the Allocator_avl's used for the TX packet allocators of the Nic
  and Uplink Connection with the better suited Nic::Packet_allocator.
