spinlock: fix build with older GCC

Older GCC versions such as 4.3 cannot have initializers for the
members of anonymous structures, so initialize .head_tail instead.

Use a SPINLOCK_TICKET_INC define so this initializer is near the
spinlock_tickets_t definition (in case the structure changes requiring
changes to the initializer).
