* Remove Handbrake patch as it was integrated upstream
* Remove version restrictions in the specfile as almost all of them have
been long surpassed
* Refresh VP9 decoder patch from Intel
* Remove libpostproc package as it is no longer a separate so
* Disable libplacebo in the build as 7.351.0 is required with this
version of libavformat. Fedora is on 7.349 and Terra has obsoleted its
coverage of this package.
* Bump all soversions to match upstream
