[Buildroot] [git commit] package/opencv: drop gstreamer 0.10.x support

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=0220ad8b138da666fd546d749674dcbde1ecb12a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

With the upcoming removal of gstreamer 0.10, the logic for building opencv
with support for it must go as well.

As there is now a single option for gstreamer (1.x) support, convert the
gstreamer support choice to a normal option for simplicity.
