t/helper: don't depend on implicit wraparound
In our test helpers we have two cases where we assign -1 to an `unsigned
long`. The intent is to essentially mean "unbounded output", which is
achieved via implicit wraparound of the value.
This pattern causes warnings with -Wsign-compare though. Adapt it and
instead use `ULONG_MAX` explicitly.
