internal/gocore: don't panic if backtrace fails

Backtracing a thread in the core file may fail for various reasons: it
might have C functions, which we don't know how to deal with, or its
stack could be corrupted. Don't crash if that happens, just give up on
backtracing the current thread.

Fixes golang/go#27323
