[meta-freescale] [PATCH] gstreamer1.0-plugins-bad: fix build for opencv >= 3.4.2

[Gary Bisson]

Since OpenCV was updated to version 3.4.3 in meta-openembedded:
7b9f86ca7 opencv: Update to 3.4.3

The gstreamer-plugins from NXP is therefore out of sync and can't build
without this patch from upstream.
