feh_http_load_image: Use mkstemps to save image with correct suffix
This allows feh to load .gif images via libcurl, as some imlib2 versions only load gif images if the suffix is correct. It's also more convenient when using --keep-http. To achieve this, feh needs to use mkstemps. mkstemps is a non-standard extension that is available on several systems. Compile feh with "mkstemps=0" to use mkstemp instead. Closes #630
