[dpdk-dev] [PATCH] common/mlx5: fix dlopen meson build

The glue shared library name was created by the common class FMT name,
driver_name_fmt = 'rte_common_ at 0@', which is not correlated with
LIB_GLUE_BASE = 'librte_pmd_mlx5_glue.so'.

This causes the dynamic linkage of the glue library to fail what
remained mlx5 drivers outside the PCI driver list.

The command:
MLX5_GLUE_PATH=$(pwd)/build-meson/drivers/common/mlx5
build-meson/app/dpdk-testpmd -n 4  -w 0000:00:05.0 -w 0000:00:06.0 -- -i

The log:
common_mlx5: Cannot load glue library:
/usr/local/lib64/dpdk/pmds-20.0.1-glue/librte_pmd_mlx5_glue.so.20.02.0:
cannot open shared object file: No such file or directory

Adjust the shared library name to the LIB_GLUE_BASE definition.

Fixes: 7b4f1e6bd367 ("common/mlx5: introduce common library")
