contrib/rdmacm-mux: fix clang compilation

Fix Commit a5d2f6f (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.
