sys_clock.h: Remove variance of _TICK_ALIGN with TICKLESS_KERNEL

Browse source 
Not sure why this was here.  The point to this API (which is poorly
explained) is to "round up" requested timeout values to an integer
number of ticks in the future, so the timeouts don't expire too soon.

There's no change of that requirement in tickless mode.  While the
"tick" unit will typicaly be a much smaller time (and thus much less
likely to have this kind of aliasing bug), we STILL don't want early
expiration.

And as with everything else in tickless, changing this breaks no
tests.  So remove it as a needless TICKLESS dependency.
