cputime: Default implementation of nsecs -> cputime conversion
The architectures that override cputime_t (s390, ppc) don't provide
any version of nsecs_to_cputime(). Indeed this cputime_t implementation
by backend only happens when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y under
which the core code doesn't make any use of nsecs_to_cputime().
At least for now.
We are going to make a broader use of it so lets provide a default
version with a per usecs granularity. It should be good enough for most
usecases.
