Replace vp9 with vp09... in MediaCapabilities LayoutTests

vp9 is ambiguous about important details like codec profile.
vp09.... specifies the missing details.

http://www.webmproject.org/vp9/mp4/#codecs-parameter-string

Using the ambiguous vp9 string will cause the returned
MediaCapabilitiesInfo to mark is_supported=false. The tests don't
actually check this value, but we should use the right string to
set a good example.
