Summary

• Repair the OSS EdenFS build graph and Rust/C++ backingstore bridge so the daemon and privileged helper can be built on macOS arm64 with getdeps-managed dependencies.
• Build and package the modern Python edenfsctl with its Folly and Thrift runtime when EDEN_USE_THRIFT_PYTHON_CLI=ON. The targeted build uses EDEN_BUILD_INTEGRATION_TESTS=OFF.
• Avoid selecting pipe2 in Eden common on macOS, where a binary built with the macOS 27 SDK can crash at startup on macOS 26.

Addresses #1478.

Test Plan

• A getdeps-managed source build completed on macOS arm64 with the dependency revisions pinned before the latest main update. The daemon, privileged helper, and packaged Python client built; the client started, an EdenFS NFS checkout mounted, and Bazel //:hello passed in that checkout.
• On current main, getdeps dependency resolution, cargo metadata --locked for eden/scm, and rustfmt --check for the changed Rust source passed. The external Eden common, Folly, and fbthrift patches apply to the updated pinned revisions.
• The full macOS build has not yet been rerun with the updated dependency revisions. Linux EdenFS has not been built locally.
• A macOS EdenFS CI build would provide regression coverage; the repository does not currently run one for pull requests.

Hi @maxlepikhin - thanks for the PR. I have a stack that I'm working on that should get EdenFS buildable and runnable with cmake. It's about halfway done, I'll try to get that landed ASAP and then will take a look at this PR. Even after I land my stack, I think your PR will still have changes to merge and land that my stack doesn't cover. For example, I built on macOS 26 and I see you have a macOS 27 fix.

The changes in this PR make it buildable and runnable on MacOS 26, it worked for me.
