dpdk_plugin: fix mlx5 build and runtime issues

Browse Source 
There are issues with VPP finding and linking the mlx5 shared glue
library which was built by default if mlx5 was enabled.

Runtime Errors this patch fixes:

net_mlx5: cannot load glue library: librte_pmd_mlx5_glue.so.18.05.0:
cannot open shared object file: No such file or directory

net_mlx5: cannot initialize PMD due to missing run-time dependency on
rdma-core libraries (libibverbs, libmlx5)

This patch introduces additional config parameter to disable glue
library building and instead statically link ibverbs and mlx5
libraries to the PMD and dpdk_plugin.
