strings-test.js fails on s390x

We're running into this in Ubuntu's 22.04 CI: https://autopkgtest.ubuntu.com/results/autopkgtest-jammy/jammy/s390x/n/node-nan/20220306_113841_a17b2@/log.gz

I wonder if this might be an endian issue with the usage of the Buffer class? We can disable the test but a fix/workaround would be most appreciated.
