[DEBUG] Use va_copy when reusing a va_list
When tracing (with the DEBUG compile-time option set to 1 or 2),
exverror calls TRACEV to print its arguments before passing them on.
So the arguments are consumed by the time exvwarning looks for them,
resulting in a segfault:

 $ sh -c '"'
 sh: Syntax error: Unterminated quoted string
 $ sh -o debug -c '"'
 sh: Segmentation fault (core dumped)

Make a copy with va_copy to avoid this.
