"unknown argument ignored: lazytime" in overlay operations
Metadata
Current evaluation
Triaged bug: old fuse-overlayfs versions emit noisy “unknown argument ignored: lazytime” warnings during overlay mounts; it remains open without a craft-parts fix.
Suggested action: keep open
Reason: The maintainer-authored report is marked Triaged and provides a reproducible trigger (“Build any project that has overlay-script or overlay-packages”), a log excerpt, and a linked upstream fix. The current mount wrapper still invokes fuse-overlayfs directly and no craft-parts commit addressing lazytime was found, so the valid warning-noise bug should remain open.

Issue body
### Bug Description
Recent versions of craft-parts print many `unknown argument ignored: lazytime` messages when performing overlay-related operations.
Related: https://github.com/containers/fuse-overlayfs/issues/429 . It's fixed in fuse-overlayfs [1.15](https://github.com/containers/fuse-overlayfs/releases/tag/v1.15) but that's too new for jammy & noble. Maybe we can reproduce [the fix](https://github.com/containers/fuse-overlayfs/commit/ab0b0f6d4692d13e1f8cf8a3fdf271a22dad7954) locally, or filter out the warning somehow.
### To Reproduce
Build any project that has `overlay-script` or `overlay-packages`
### part yaml
```shell
```
### Relevant log output
```shell
Initialising lifecycle
Installing build-packages
Pulling rootfs
Pulling packages
Overlaying rootfsunknown argument ignored: lazytime
```
