contrib/rdmacm-mux: fix clang compilation 

Fix Commit a5d2f6f877 (contrib/rdmacm-mux: Add implementation
                       of RDMA User MAD multiplexer).

The above commit introduces a new contrib target, adding a global dependency
to libumad library in case pvrdma configuration option is enabled.
Clang forbids it:
    clang-6.0: error: -libumad: 'linker' input unused
              [-Werror,-Wunused-command-line-argument]

Fix by limiting the scope to the rdmacm-mux target itself.
