COMP: Explicitly link RemoteIO against OpenSSL

Given that since commit r22724 curl library is linked against OpenSSL
and that since commit r22732 it is statically built. This commit
explicitly link the shared library RemoteIO against OpenSSL
because the curl static library doesn't provide information how to
resolve the OpenSSL symbol.
