Makefile.release: Replace manifest-tool with docker manifest (#4421)

This commit replaces `manifest-tool` with `docker manifest`, which should
hopefully provide a better experience for releasing coredns.

In addition it integrates mips64le (since it's supported by `docker
manifest`) in LINUX_ARCHES, so docker images for mips64le are pushed as
well.
