Don't use LIBMESH_OPTIONS in reduced basis ex5
Don't use LIBMESH_OPTIONS in reduced basis ex5

I could swear that my usual "block Jacobi + ILU4" combo has been
working fine here for years, but today I just get a convergence
failure with DIVERGED_INDEFINITE_PC.

Regressing libMesh a ways doesn't seem to help.  @pbauman is trying to
hunt down some PETSc behavior changes that hopefully will explain this
too, but in the meantime the default preconditioner settings work fine
and we should just use them.
