Make Ruby 2.4.10 work

[wjessop]

This Ruby version doesn't work locally. To re-create:

docker build . --build-arg RUBY_VERSION=2.4.10 

I think the error is something to do with uname -P returning unknown in the 2.4.10 image and that preventing the nokogiri build from completing, from /usr/local/bundle/gems/nokogiri-1.6.6.4/ext/nokogiri/tmp/aarch64-unknown-linux-gnu/ports/libxslt/1.1.28/configure.log:

configure: WARNING: if you wanted to set the --build type, don't use --host.
