Add support for M1 Silicon Macs - Can't build Netty

See original GitHub issue

I know the M1 Macs are still relatively new and not all developers have them, I decided to try to build Netty for the first time ever on my M1 Mac and it failed.

Just letting you know in case no one has tried before.

I also wonder if the NATIVE-TRANSPORTS (kqueue) will also build on M1 Macs?

Expected behavior

To be able to run mvn clean package successfully

Actual behavior

Build fails with error:
