qt4: remove already merged patch

This patch was merged into the 4.8.7 release. This was missed on
upgrade, and we didn't notice because our quilt-based patch handling
code ignores already-applied patches.

-Subject: [PATCH] Don't crash on broken GIF images
-
-Broken GIF images could set invalid width and height
-values inside the image, leading to Qt creating a null
-QImage for it. In that case we need to abort decoding
-the image and return an error.
-
-Initial patch by Rich Moore.
-
-Backport of Id82a4036f478bd6e49c402d6598f57e7e5bb5e1e from Qt 5
