[PATCH] net/mana: support rdma-core via pkg-config in meson

[PATCH] net/mana: support rdma-core via pkg-config in meson

[Shreesh Adiga]

Currently building with custom rdma-core installed in /opt/rdma-core
after setting PKG_CONFIG_PATH=/opt/rdma-core/lib64/pkgconfig/ results
in the below meson logs:
Run-time dependency libmana found: YES 1.0.54.0
Header "infiniband/manadv.h" has symbol "manadv_set_context_attr" : NO

Thus to fix this, the libs is updated in meson.build and is passed to
the cc.has_header_symbol call using dependencies. After this change,
the libmana header files are getting included and net/mana is
successfully enabled.

Fixes: 517ed6e2d590 ("net/mana: add basic driver with build environment")
