M1 Support

This tracking ticket can state the current issues blocking builds on M1 (Apple Silicon) machines.

Currently, when running on an M1 machine we will get output like this:

╰─ ~/.buck/buck build //ios:AirbnbApp
Unable to connect to Buck daemon, restarting it...
Not using buckd because daemon failed to start.

I believe the relevant snippet is (fat file, but missing compatible architecture (have 'i386,x86_64', need 'arm64e'))

Workaround is to install buck using Rosetta terminal. Afterwards buck can be used from any terminal as usual.

Follow section Configuring Rosetta for ARM64 MacBook https://github.com/valhalla/valhalla#configuring-rosetta-for-arm64-macbook . After that use Rosetta terminal with ibrew and follow section Build from Source from https://buck.build/setup/getting_started.html .

@ajanuar I published my PR, feel free to try it 😃 but be aware, Java 8 support is dropped due to upstream changes.
