chrt: add support for SCHED_RESET_ON_FORK

Subject: [PATCH] Add support for SCHED_RESET_ON_FORK to chrt
SCHED_RESET_ON_FORK has been added in 2.6.31. If a thread has this flag
set, chrt reports "unknown" policy, which is confusing.
The patch adds support for this new flag. It will (can) only be applied
to SCHED_FIFO or SCHED_RR, so there's no need to catch the other
scheduling policies.
