#2772: FFMPEG -strict -2 and -strict experimental do not get applied with vp9

Summary of the bug:
I'm trying to use the experimental branch of libvpx to test vp9, but
ffmpeg won't use libvpx-vp9 even though '-strict -2' is specified. The
option gets parsed but apparently not applied.
How to reproduce:
Compile the experimental branch of libvpx, enable vp9 and enable shared
libraries. Compile ffmpeg with libvpx enabled. The following output is
produced:

Last message repeated 3 times
Codec AVOption strict (how strictly to follow the standards) specified for
output file #0 (test2.mkv) has not been used for any stream. The most
likely reason is either wrong type (e.g. a video option with no video
streams) or that it is a private option of some encoder which was not
actually used for any stream.
Codec AVOption b (set bitrate (in bits/s)) specified for output file #0
(test2.mkv) has not been used for any stream. The most likely reason is
either wrong type (e.g. a video option with no video streams) or that it
is a private option of some encoder which was not actually used for any
stream.
[libvpx-vp9 @ 0x169abe0] The encoder 'libvpx-vp9' is experimental but
experimental codecs are not enabled, add '-strict -2' if you want to use
it.
