gl: Add opengl_version.h to the list of sources

Adding this private header to the list of sources. We don't want to make
this header public, but we need it in the list of sources otherwise it
won't be included in the tarball. This fixes make distcheck.

This regression was introduced by commit 1a6fe3db
