Danny Povolotski 27b5f761b1 avoid copying extended file attributes when inside virtiofs (#57555)
Summary:
I'm doing CI/CD that includes React Native inside of https://tart.run/. Tart uses Apple Virtualization Framework, which in turn mounts VirtioFS volumes.

This feels like a common enough use case to contribute upstream, since I can envision many more people using Apple's virtualization features.

## Changelog:

[GENERAL] [FIXED] - react-native-codegen build.sh on AppleVirtIOFS volumes

Pull Request resolved: https://github.com/react/react-native/pull/57555

Test Plan: Run `packages/react-native-codegen/scripts/oss/build.sh` inside a virtual machine that uses Apple Virtualization Framework such as Tart
