avfilter/vf_stack: Don't modify const strings b3b7ba62 introduced undefined behaviour: A (non-modifiable) string literal has been assigned to a modifiable string; said string was indeed modified later via av_strtok. This of course caused compiler warnings because of the discarded qualifier; these are in particular fixed by this commit.
