Fix times return value, CLK_TCK description
[BZ #2636]
* manual/time.texi (Processor Time): Return type of times is
elapsed real time since an arbitrary point in the past.
(CPU Time): Move CLK_TCK from here...
(Processor Time): ...to here. Correct description.
* manual/conf.texi (Constants for Sysconf): Correct description of
_SC_CLK_TCK.
