Bug#911846: diffoscope: test failures in stretch-backports

[Mattia Rizzolo]

Source: diffoscope
Version: 104
Severity: minor

Trying to build v104 in stretch-backports, one end up with this test
failure, introduced with the new ocaml comparator.

I just hope we won't need to do something like the haskell comparator,
which test basically never run... :(
