net/mlx: remove separate ABI version for glue libraries

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.
