Amir Goldstein 6f5ba68b7b overlay: rename OVERLAY_LOWER/UPPER/WORK_DIR
As preparation step for configuring test/scratch base fs
for overlay tests:

- Rename OVERLAY_LOWER/UPPER/WORK_DIR => OVL_LOWER/UPPER/WORK
  because we want to use OVL_ prefix for all base fs vars

- Prepend "ovl-" prefix to lower/upper/work path values to
  isolate the overlay test dirs when running on a base fs
  that is also used to run non overlay tests

- Make those vars values non-configurable, because lower/upper/work
  directory names are an internal test detail which should
  not concern the user and because we wish to simplify
  and document the overlay tests setup

- Add helper _filter_ovl_dirs and use it to filter output
  of test overlay/023 which matches the constant string "work"

# The upper dentry may become stale before we remove it from
# overlay, e.g. file was removed from upperdir directly, which
# triggered warning/oops in ovl_remove_and_whiteout().
#
# Commit cfc9fde0b07c ("ovl: verify upper dentry in
# ovl_remove_and_whiteout()") fixed this issue.
