TestImageOperationsGolden fails on aarch64, ppc64le, s390x

[QuLogic]

TestImageOperationsGolden was failing on these arches in 0.58.3 as reported in #6387, and should have been fixed by #6396. This is true: if I build 0.58.3, then it fails just like the original report, but building 0.58.3 + a backported patch works. However, between that time and 0.59.0, it seems to have broken again. According to a bisect on a ppc64le test machine, this began with 4b286b9:

What version of Hugo are you using (hugo version)?

0.59.0

Does this issue reproduce with the latest release?

Yes.

[bep]

Yea, this was kind of expected. I think we need a test fix for this that is a little more robust.

[bep]

/cc @anthonyfok

[QuLogic]

Seems to be fixed in 0.59.1, probably by #6458.

[anthonyfok]

Hi @QuLogic, thank you for the report!

Sorry, I didn't see your report till just moments ago. Hope that the use of Travis CI’s arm64 build (see PR #6467, committed to master as ae4fde0) will help us catch similar cases sooner in the future.
