Allow selectors in exec policy selection rules co contain lists.
Allow selectors in exec policy selection rules co contain lists.

This allows selectors for exec policy selection rules to contain
not just single string values, but also lists,
the same way as filesystem virtualisation rules already do.
Rule containing list as a selector matches any element of the list.

Internal ruletree representation has not been changed,
just lua scripts were updated to add internal rule for each list element.
