builtin-apply.c: get rid of an unnecessary use of temporary array
Instead of allocating a temporary array imglen[], copying contents to it from another array img->line[], and then using imglen[], use the value from img->line[], whose value does not change during the whole process. This incidentally removes a use of C99 variable length array, which some older compilers apparently are not happy with. Signed-off-by: Junio C Hamano <gitster@pobox.com>
