    PR10177: init/kill time in sleepy context only
    
    Previously, _stp_init_time and _stp_kill_time were being called from
    begin/end/error probes, which will run with preemption disabled.  The
    BUG reported on RT kernels showed that cpufreq_unregister_notifier can
    end up sleeping, which violates our preemption block.
    
    This patch moves the init/kill into systemtap_module_init/exit, where it
    is safe to sleep.  The code maintains a new predicate with the define
    STAP_NEED_GETTIMEOFDAY, so we don't still incur any timer overhead if
    it's not used.
