OBS native plugins should install their .so files to lib/obs-plugins/
and data files to share/obs/obs-plugins/ and they will be automatically
loaded, when obs installed in the same profile (directories for finding
plugins defined in native-search-paths of obs package).  Also, take a
look at obs-* packages for examples on how to package plugins.

There was no scripts support, updated obs package to 27.2.4 and enabled
python and lua scripting support.
