selftests/bpf: Fix endianness issue in __qspinlock declaration

Browse Source 
Copy the big-endian field declarations from qspinlock_types.h,
otherwise some properties won't hold on big-endian systems. For
example, assigning lock->val = 1 should result in lock->locked == 1,
which is not the case there.
