[Test] allow infeasible problems to also return INFEASIBLE_OR_UNBOUNDED

[odow]

Cbc returns INFEASIBLE_OR_UNBOUNDED here, which is reasonable: https://github.com/jump-dev/Cbc.jl/blob/43e5ecccdccee10a0ac2e5c8566330ce1910b2c7/test/MOI_wrapper.jl#L49-L51

There are already a bunch of other tests with a similar check:

MathOptInterface.jl/src/Test/test_conic.jl
