runtime: properly frame panic values in tracebacks
This CL causes the printing of panic values to ensure that all
newlines in the output are immediately followed by a tab, so
that there is no way for a maliciously crafted panic value to
fool a program attempting to parse the traceback into thinking
that the panic value is in fact a goroutine stack.
