runtime: in traceback, print panic rather than runtime.gopanic

Browse Source 
The gc toolchain does the same thing, in gentraceback in
    runtime/traceback.go.
    
    The test for this is TestPanicTraceback in runtime/crash_test.go.  We
    don't yet run that test, but we will in a future change.
