fix(linux): Add Supported Colorimetries to Wave5

There have been a few cases where pipelines fail to negotiate despite
the resolutions and pixel formats being compatible with Wave5
requirements. The negotiation comes from gstreamer plugin not supporting
the colorimetry the video was encoded with. Add the list of supported
colorimetries the gstreamer V4L2 plugin can work with.
