Russ Cox bcfe519d58 runtime: fix correctness test at end of traceback
We were requiring that the defer stack and the panic stack
be completely processed, thinking that if any were left over
the stack scan and the defer stack/panic stack must be out
of sync. It turns out that the panic stack may well have
leftover entries in some situations, and that's okay.

Fixes #8132.
