Replace fcntl-based file lock with flock
WSL1 does not support `fcntl`-based lock and will always report success, therefore creating a race condition when multiple rustc processes are modifying shared data such as `search-index.js`. WSL1 does however support `flock`. `flock` is supported by all unix-like platforms. The only caveat is that Linux 2.6.11 or earlier does not support `flock` on NFS mounts, but as the minimum supported Linux version is 2.6.18, it is not an issue. Fixes #72157
