[Buildroot] [PATCH v6 09/16] package/opencv: add a choice for selecting gstreamer support

[Samuel Martin]

OpenCV 3.0 support both gstreamer-0.10 and gstreamer-1.x, but only one
is used at the time.

This patch turns the gstreamer support into a choice, in order to prepare
adding the support for gstreamer-1 in a following patch.
