Continue handling signals after disabling forwarding
Before destroying the Kernel, we disable signal forwarding, relinquishing control to the Go runtime. External signals that arrive after disabling forwarding but before the sandbox exits thus may use runtime.raise (i.e., tkill(2)) and violate the syscall filters. Adjust forwardSignals to handle signals received after disabling forwarding the same way they are handled before starting forwarding. i.e., by implementing the standard Go runtime behavior using tgkill(2) instead of tkill(2). This also makes the stop callback block until forwarding actually stops. This isn't required to avoid tkill(2) but is a saner interface.
