This implements readonly mounting of /sysroot for composefs systems, matching the behavior that ostree systems already have. Previously, composefs left /sysroot mounted read-write, which was inconsistent and meant the readonly tests had to be skipped for composefs. The implementation uses a direct `libc::syscall` wrapper for `mount_setattr` since rustix doesn't yet provide this API. The `MOUNT_ATTR_RDONLY` flag is applied to three mount points during initramfs setup: - The composefs rootfs image mount (becomes `/` after switch-root) - The test root filesystem mount (used in testing scenarios) - The sysroot clone mount (becomes `/sysroot` in the booted system) With this change, the readonly /sysroot tests in test-status.nu now run for both ostree and composefs systems without conditional checks.

Run integration test locally
In the bootc CI, integration tests are executed via Packit on the Testing Farm. In addition, the integration tests can also be run locally on a developer's machine, which is especially valuable for debugging purposes.
To run integration tests locally, you need to install tmt and provision-virtual plugin in this case. Be ready with dnf install -y tmt+provision-virtual. Then, use tmt run -vvvvv plans -n integration command to run the all integration tests.
To run integration tests on different distros, just change image: fedora-rawhide in 9d15eedea0/tmt/plans/integration.fmf (L6).
The available images value can be found from https://tmt.readthedocs.io/en/stable/plugins/provision.html#images.
Enjoy integration test local running!
