[PATCH v2 0/6] fstests overlay fixes for v2025.05.25

[Amir Goldstein <amir73il@gmail.com>]

Zorro,

My first batch of fixes [1] was addressing overlayfs test failures after
upgrade of test machine to a newer distro (trixie) with libmount v1.41.

After a closer look, I found some tests that regressed into _notrun,
which is harder to notice at first glance.

Tests generic/{633,697,697} were regressed in v2025.03.17.
Test generic/699 always had a problem AFAICT, but I only just tested
it with custom MOUNT_OPTIONS.

Lastly, following the review discussion between Miklos and Karel Zak,
I changed the workaround to the regressions observed after upgrade to
newer libmount.

Thanks,
Amir.

Changes since v1 [1]:
- Change workaround from LIBMOUNT_FORCE_MOUNT2 to --options-mode=ignore
- Add two commits to fix tests that were not running by mistake
