  The glue libraries are tightly bound to the mlx drivers of a dpdk version
and are packaged with them.

Keeping a separate ABI version prevents us from installing two versions of
dpdk.
Maintaining this separate version just adds confusion.
Align the glue library ABI version to the global ABI version.

Looks safe and provides an automatic ABI version update for mlx*_glue modules.
