[Merge M67] Map U+04CF to lowercase L as well.

U+04CF (ӏ) has the confusability skeleton of 'i' (lowercase
I), but it can be confused for 'l' (lowercase L) or '1' (digit) if rendered
in some fonts.

If a host name contains it, calculate the confusability skeleton
twice, once with the default mapping to 'i' (lowercase I) and the 2nd
time with an alternative mapping to 'l'. Mapping them to 'l' (lowercase L)
also gets it treated as similar to digit 1 because the confusability
skeleton of digit 1 is 'l'.
