sched/cputime: Add steal time support to full dynticks CPU time accounting
This patch adds guest steal-time support to full dynticks CPU
time accounting. After the following commit:
ff9a9b4c4334 ("sched, time: Switch VIRT_CPU_ACCOUNTING_GEN to jiffy granularity")
... time sampling became jiffy based, even if we do the sampling from the
context tracking code, so steal_account_process_tick() can be reused
to account how many 'ticks' are stolen-time, after the last accumulation.
