runtime: ignore __morestack function in runtime.Callers
Backport from trunk.
We were ignoring all functions starting with "__morestack_", but not
the function "__morestack" itself. Without this change, some tests
such as recover.go started failing recently, though I'm not sure
exactly what changed.
