cmake: OSG plugins lib-prefixed name
With a regular static osg build, the plugins have lib-prefixed names such as libosgdb_jpeg.a
However, as of a58a8db0 (@AnyOldName3), cmake/FindOSGPlugins.cmake
tries to find osgdb_jpeg.a
which does not exist.
The Android build works around this by patching OSG but wouldn't it be better to fix it here by reverting the aforementioned commit?
