runtime: fail silently if we unwind over sigpanic into C code If we're running C code and the code panics, the runtime will inject a call to sigpanic into the C code just like it would into Go code. However, the return PC from this sigpanic will be in C code. We used to silently abort the traceback if we didn't recognize a return PC, so this went by quietly. Now we're much louder because in general this is a bad thing. However, in this one particular case, it's fine, so if we're in cgo and are looking at the return PC of sigpanic, silence the debug output. Fixes #23576.
