  Append to CLONE_USERS and CLONE_GROUPS by using +=

- instead of expanding the previous value to an empty element, which then
causes problems later (introduced in #699 to pacify set -ue in bash 3).

The fix is still compatible with bash 3 and set -ue.

XXX similar changes should be applied to other numerous array operations found
in this file.

Fixes #2220
