Makefile: fix abi build using romio

We no longer have any convenience libraries that need go into libmpi.so
when libpmpi.so is also built. Thus, the legacy mpi_convenience_libs
variable is no longer in use. However, we need differentiate libromio
from the other convenience libraries for the ABI build. ROMIO depends on
MPI, thus will need separate version for ABI and non-ABI build. Thus, we
create two variables -- mpi_convenience_libs and abi_convenience_libs.
Note: the former reuses the name but now with different meanings.
