runtime: give test child time to block The child in TestPanicSystemstack prints "x\n" and then blocks on a lock. Receiving those bytes only indicates that the child is _about to block_. Since we don't have a way to know when it is fully blocked, sleep a bit to give it time to block. This makes us less likely to lose the race and signal before the child blocks, which will fail the test as the stack trace cannot be read from a running G.
