[opus/x265] Fix version in pkgconfig

[JackBoosY]

Version control file (such as .git) is used in the source to extract the version number, but this is not available in the direct download package.
Add a fixed patch and pass in the version number to avoid extra changes to the source files.

Fixes #26369.
Fixes #25680.
