1. vz: configure Rosetta’s ahead of time (AOT) caching options using an … …

   …abstract socket
   
   This change allows starting the `/mnt/lima-rosetta/rosttad daemon` in the VM.
   Without this change, it cannot be started as shown below:
   ```console
   $ sudo /mnt/lima-rosetta/rosettad daemon
   rosetta error: Failed bind socket: 98
   Trace/breakpoint trap
   ```
   
   Since `rosettad` needs to run in the same namespace as `rosetta` and must be executed directly from `/mnt/lima-rosetta/rosettad` (copies of `rosettad` do not work), it is difficult to use during container image builds or similar processes.
   
   In a container, `rosettad` can be run as follows:
   ```console
   $ docker run -it --rm --platform linux/amd64 --name test-rosettad -v/mnt/lima-rosetta:/mnt/lima-rosetta ubuntu
   root@45f887cb0eaa:/# ls -la ~/.cache/rosettad
   /usr/bin/ls: cannot access '/root/.cache/rosettad': No such file or directory
   root@45f887cb0eaa:/# /mnt/lima-rosetta/rosettad daemon&

   root@45f887cb0eaa:/# ls -la ~/.cache/rosettad

   ```
   
   Even if `rosettad` is not running, it does not affect the operation of `rosetta`, so the existing functionality remains unchanged.
   
   There is also a configuration to use Unix Domain Sockets instead of Abstract Sockets. However, it appears that some preparation is required on the VM guest side before mounting, and I was unable to make it work. Therefore, I am using the configuration with Abstract Sockets.
