Bug#44020 Unicode Swedish collations not working with IBMDB2I

The utf8_swedish_ci and ucs2_swedish_ci
collations do not work with indexes on 
IBMDB2I tables.

The current patch adds the mapping for
ucs2_swedish collation and removes the 
ucs2_spanish2 mapping which is not
supported by any version of the operating
system.
