selftests/futex: Give circular-list nodes static storage

Browse Source 
The registered robust-list head has static storage but points at three
automatic lock nodes. GCC warns about storing the address of a local
variable in the static head when building the selftest with -Wall.

Give the nodes static storage as well. This keeps every object in the
circular list alive through child exit without changing the list topology.
