Tell trace-cmd that the "tai" clock source should be displayed in seconds
and needs to be parsed as such.

Instead of:

    sleep-2084  [001]1651097314396951318: function:             __mutex_unlock_slowpath
    sleep-2084  [001]1651097314396951516: function:             ktime_get_mono_fast_ns
    sleep-2084  [001]1651097314396951773: function:             ktime_get_mono_fast_ns
    sleep-2084  [001]1651097314396951773: function:             rcu_read_lock_sched_held
    sleep-2084  [001]1651097314396951949: function:             ktime_get_mono_fast_ns
    sleep-2084  [001]1651097314396952359: function:             ktime_get_mono_fast_ns

Display as:

    sleep-2084  [001] 1651097314.396951: function:             __mutex_unlock_slowpath
    sleep-2084  [001] 1651097314.396952: function:             ktime_get_mono_fast_ns
