[Buildroot] [PATCH v3 1/3] gst-ffmpeg: add option to select GPL vs LGPL build

[Danomi Manchego]

Signed-off-by: Danomi Manchego <danomimanchego123 at gmail.com>

---

v2 -> v3:
 - Change enable-LGPL option to an enable-GPL, like the ffmpeg
   option, per recommendation from Luca Ceresoli.

v1 -> v2:
 - Move GST_FFMPEG_CONF_OPT adjustment (introduced by this patch)
   higher in the file, so that GST_FFMPEG_CONF_EXTRA_OPT lines
   don't get split.
