rCOMM92217b6a85b5: [nix] Fix xcodebuild command

Summary

At some point, Nix started setting the $DEVELOPER_DIR env var, which breaks xcodebuild (which internally calls xcrun).

Some context on this GitHub issue. Deeper explanation from ChatGPT here.

Test Plan

Confirm xcodebuild no longer prints error: tool 'xcodebuild' not found when run in Nix environment

Harbormaster failed remote builds in B35768: Diff 50366!

I'm going to land this one without review as it's a simple change and clearly breaking things. The CI is still failing because we run buildkite-agent from within Nix... to fix it I need to land this diff, then run git pull and reenter the Nix environment on all runners.
