tick/sched: Hide unused oneshot timer code

A couple of functions in kernel/time/tick-sched.c are only
relevant for oneshot timer mode, i.e. when hires-timers or
nohz mode are enabled. If both are disabled, we get gcc warnings
about them:

kernel/time/tick-sched.c:98:16: warning: 'tick_init_jiffy_update' defined but not used [-Wunused-function]
 static ktime_t tick_init_jiffy_update(void)
                ^
kernel/time/tick-sched.c:112:13: warning: 'tick_sched_do_timer' defined but not used [-Wunused-function]
 static void tick_sched_do_timer(ktime_t now)
             ^
kernel/time/tick-sched.c:134:13: warning: 'tick_sched_handle' defined but not used [-Wunused-function]
 static void tick_sched_handle(struct tick_sched *ts, struct pt_regs *regs)
             ^

This encloses the whole set of functions in an appropriate ifdef
to avoid the warning and to make it clearer when they are used.
