That's weird, a directory with the old name is tried to be created in
the new 9.6 cluster if I follow that correctly.

Based on the information you gave out, a tablespace and visibly a
custom type, I have tried a 9.4->9.6 upgrade with this schema and
things are working for me with -k:
CREATE TABLESPACE popo LOCATION '$TBSPACE_DIR';
CREATE TYPE yoyo AS (a int);
CREATE TABLE toto (a int PRIMARY KEY, b yoyo) TABLESPACE popo;

The old and new tablespaces are in correct shape, even if I did not
provide a tablespace map.

Could you provide more details about the schema causing this error? Do
you have for example some roles beginning with "pg_" as prefix?
