hrtimer: Split out hrtimer defines into separate header 



To avoid include dependency hell split out the hrtimer defines which are
required in the upcoming VDSO library into a separate header file.

[ tglx: Split out from the VDSO library patch and included ktime.h as
        the new header depends on it. ]
