parlib: Use a relative timer for abort_sysc

The issue is that the timer goes off before the syscall could block.  If
the timer was very far in the past, such as due to a go test that put the
alarm 30 seconds in the past, we would do N loops, each of which fires
instantly, until we finally set an alarm for the future.

Using a relative timer fixes that.  Also, one second is a bit much - enough
that an interactive user might notice and wonder if something is broken.
