configure.ac: Remove redundant libglvnd stanza

There were two "libglvnd configuration" section in the squashed commit
that added libglvnd support, while only one in the original libglvnd
branch. A following commit moves one of them downwards. Now remove the
upper "older" one and move GL_LIB name decision downwards after the new
libglvnd configuration section.
