Due to changes in the output of hilb in singular 4.3.2p4 (it now outputs a polynomial instead of a list of monomials and coefficients to debug), some tests are failing.

Additionally, the problematic hilbert_numerator example now correctly throws an overflow error instead of giving a wrong answer. We mark it as known bug so the test passes with older versions of singular, the label can be removed once we require 4.3.2p4.

sagemathgh-36018: Fix tests with singular 4.3.2p4
    
Due to changes in the output of `hilb` in singular 4.3.2p4 (it now
outputs a polynomial instead of a list of monomials and coefficients to
debug), some tests are failing.

Additionally, the problematic `hilbert_numerator` example now correctly
throws an overflow error instead of giving a wrong answer. We mark it as
`known bug` so the test passes with older versions of singular, the
label can be removed once we require 4.3.2p4.
