cputime: Move default nsecs_to_cputime() to jiffies based cputime file

If the architecture doesn't provide an implementation of
nsecs_to_cputime(), the cputime accounting core uses a
default one that converts the nanoseconds to jiffies. However
this only makes sense if we use the jiffies based cputime.

For now it doesn't matter much because this API is only
called on code that uses jiffies based cputime accounting.

But the code may evolve and this API may be used more
broadly in the future. Keeping this default implementation
around is very error prone as it may introduce a bug and
hide it on architectures that don't override this API.

Fix this by moving this definition to the jiffies based
cputime headers as it is the only place where it belongs to.
