typelib file generation

[orenskl]

Currently all typelib files are not generated via the build system. They are part of the git repository:

• https://github.com/orenskl/HiFiStreamer/tree/c6e7f34d78608dff78eae82d99f2eca8bbd26815/packages/devel/gi/files
• https://github.com/orenskl/HiFiStreamer/tree/c6e7f34d78608dff78eae82d99f2eca8bbd26815/packages/multimedia/gstreamer/gstreamer/files
• https://github.com/orenskl/HiFiStreamer/tree/c6e7f34d78608dff78eae82d99f2eca8bbd26815/packages/multimedia/gstreamer/gst-plugins-base/files

These files should be generated by the build system.
