Add ARM build to CI

[shawnrader]

I can get to this next week.

When building dockerfiles for lotus and boost on native arm platform (like Mac M1) we are forced to build filecoin-ffi from source as there are no prebuild Linux arm binaries. Having it would speed up the docker builds.

Also it, perhaps, would require some change in install-filcrypto file: the line local __release_name="${__repo_name}-$(uname)-${release_flag_name}". Now it according uname always downloads Linux binaries that are only x86 compatible.

@vmx , any anticipated timing for this? if you need help in getting done, @airenas , do you have some time to help?

[airenas]

I see Draft #287, perhaps, you just need to finalize it.

[vmx]

@LaurenSpiegel Currently don't have any plans for implementing this. If there's a need for fixing this issue, perhaps @shawnrader may also be able to help.

I linked a pull request to add aarch64 Linux build, test, and publish to CI. Apple M1/M2 support will need to be done as a different task and right now CircleCI only supports cross compilation from Intel Mac.

This issue for tracking mac M1 builds: #216
