v4l2codecs: vp9: Fix reset_frame_context parameter
...
It was assumed that the kernel parameters would match with the bitstream value
but instead the author when with another set of value. Surprisingly, this
makes no difference with the resulting fluster score.

v4l2codecs: Fix debug assertion in register functions
...
As now, we warn if the decoder have no support src pixel format, but that
warning is called before the type (hence the debug category) is initialized.
Fix this by moving the debug category init out of the type initialization,
into the register funcitons.
This will fix an assertion that occures in the register function and allow
relevant log to be seen by the users.

v4l2codecs: Unify the src template caps format

Notably NV12_4L4 ended up being applied to only VP9 decoder. This fixes the
situation by using a central define for all static src pad templated formats.

v4l2codecs: vp9: Remove uneeded picture data
...
The GstV4l2Request now holds a reference on the picture buffer and is
recounted already. This effectively removes usage of GRefCount which is only
available in GLib 2.58, while we support 2.56.
Fixes #910
