Move the fake usnic IBV provider out of common/verbs and into a new common/verbs_usnic component that is always statically linked into libopen-pal. The fake provider is registered with libibverbs at run time, but there is no *un*register IBV API. Hence, we can't let the code containing this provider be dlclosed -- which means it needs to be statically linked into libopen-pal. Fixes open-mpi/ompi#1060.
