Combine these two helpers into a single generic function so that we can
use it in the next patch to test a regression when running overlayfs
atop xfs.

The tests with multi lower layers rotate the upper layer into a lower
layer on specific operations such as mkdir, rename and link.
That provides test coverage for redirect_dir and index features.
The following variations are covered:
1. All layers all on scratch fs (--ov=10 --samefs)
2. All layers on scratch fs expect for lowermost on test fs (--ov=10)
3. Lowermost layer on test fs, one layer on tmpfs and the rest
on sratch fs (--ov=10 --maxfs=1)
4. Lowermost layer on test fs, one layer on scratch fs and the rest
are unique tmpfs instances (--ov=10 --maxfs=10)
