Ignore kernel-only stacks.

Browse Source 
It is common to receive duplicate stack traces for the same timestamp
(and thread), one containing proper user-space stack, and the second one
containing only kernel frames. Discard the second one, as there's no
documentation how this should be interpreted and the kernel stack is
mostly useless.
