Currently, when printing tracebacks of other threads during GOTRACEBACK=crash, if the thread is on the system stack we print only the header for the user goroutine and fail to print its stack. This happens because we passed the g0 to traceback instead of curg. The g0 never has anything set in its gobuf, so traceback doesn't print anything. Fix this by passing _g_.m.curg to traceback instead of the g0. Fixes #19494. Fixes #19637 (backport).
