Correct syntax

Delete the "z" in av_malloc_array, this gave me an error when building in Arch Linux

/home/adro/Applications/AUR/xstudio/src/xstudio/src/plugin/media_metadata/ffprobe/src/ffprobe_lib.cpp:105:35: error: ‘av_mallocz_array’ was not declared in this scope; did you mean ‘av_malloc_array’?

thanks for spotting this, sorry it took so long to merge! Looks like av_mallocz_array is marked as deprecated in the ffmpeg version we have been using and I presume removed in yours.
