REORG: sched: moved samp_time and idle_time to task.c as well

The idle time calculation stuff was moved to task.h by commit 6dfab112e
("REORG: sched: move idle time calculation from time.h to task.h") but
these two variables that are only maintained by task.{c,h} were still
left in time.{c,h}. They have to move as well.
