test images: Fixes echoserver s390x image

When trying to build the s390x image, it would fail when running the apk
command with the following error:

ERROR: Unable to open root: Bad address
ERROR: Failed to open apk database: Bad address

This can be fixed by updating the third_party/multiarch/qemu-user-static/register/register.sh
and third_party/multiarch/qemu-user-static/register/qemu-binfmt-conf.sh scripts
and their usage to a newer version [1].

Additionally, the packages nginx-mod-http-lua and nginx-mod-http-lua-upstream
cannot be found in the regular http://dl-cdn.alpinelinux.org/alpine/v3.9/main/s390x/
repository, but we can use an older one [2].
