[zorg] Remove llvm-avr-linux builder + worker

[aaron.ballman]

Summary

This bot has been down for 14 weeks and I have been unable to reach the listed admin to determine if they're planning to bring it back online or not. Rather than leave the dead bot in the lab, let's remove it for now.

I also have tried to contact @dylanmckay about this builder without any luck.

The patch looks good.
But let's wait for a few days to see if Dylan would respond here, before proceeding with the removal, shall we?

Sounds good to me! How about if we don't hear back by next Tue (4/11), we'll land this?

FWIW, I plan to land this at some point today unless I hear otherwise.
