How about something like:

CREATE EXTENSION myextension ... SCHEMA myschema;

And in the .sql file in the extension you could have special markers for 
the schema, something like:

CREATE FUNCTION otherfunction() AS ...;
CREATE FUNCTION foo() AS $$ SELECT 'foo', @extschema(at)(dot)otherfunction() $$;

@extschema@ would be search&replaced at CREATE EXTENSION time with the 
schema specified by the user.
