Fix times return value, CLK_TCK description

Browse source 
[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.

@deftypefun clock_t times (struct tms *@var{buffer})
The @code{times} function stores the processor time information for
the calling process in @var{buffer}.
The return value is the calling process' CPU time (the same value you
get from @code{clock()}. @code{times} returns @code{(clock_t)(-1)} to
indicate failure.
The return value is the number of clock ticks since an arbitrary point
in the past, e.g. since system start-up. @code{times} returns
@code{(clock_t)(-1)} to indicate failure.
