[opus] Misc patches

[Ralph Giles]

Speaking of needing more complete ci feedback, the intrin0.h patch
broke the appveyor build:

> Microsoft (R) Build Engine version 14.0.25420.1
> [...]
> :\projects\opus\celt\ecintrin.h(53): fatal error C1083: Cannot open
include file: 'intrin0.h': No such file or directory
[C:\projects\opus\win32\VS2015\opus.vcxproj]

https://ci.appveyor.com/project/rillian/opus/builds/33474422

Is this an extra feature the appveyor environment doesn't apply, or is
the version guard incorrect?
