selftests/futex: Remove static keyword from 'head'

'head' is defined as 'static struct robust_list_head' that stores the
local variable of 'struct lock_struct a' raising the Wdangling-pointer
warning.

robust_list.c: In function ‘child_circular_list’:
robust_list.c:522:24: warning: storing the address of local variable
‘a’ in ‘head.list.next’ [-Wdangling-pointer=]

  522 |         head.list.next = &a.list;
      |         ~~~~~~~~~~~~~~~^~~~~~~~~
robust_list.c:513:28: note: ‘a’ declared here
  513 |         struct lock_struct a, b, c;
      |                            ^
robust_list.c:512:40: note: ‘head’ declared here
  512 |         static struct robust_list_head head;
      |                                        ^~~~

Since 'head' doesn't need static storge duration, removing the static
keyword of it to fix this.
