select: add a poll specific struct to the restart_block union
with hrtimer poll/select, the signal restart data no longer is a single
long representing a jiffies count, but it becomes a second/nanosecond pair
that also needs to encode if there was a timeout at all or not.
This patch adds a struct to the restart_block union for this purpose
