[klibc] dash: [BUILTIN] Remove unnecessary restoration of format string in
printf

[ dash commit 7bb413255368e94395237d789f522891093c5774 ]

Currently we try to preserve the format string which is stored in
argv after temporarily modifying it.  This is unnecessary as it's
only ever used once.  This patch gets rid of it.
