whence -a: fix spurious 'undefined function' message

Browse source 
$ ksh -c 'whence -a printf'
	printf is a shell builtin
	printf is /usr/bin/printf
	printf is an undefined function

The third line should not appear.

src/cmd/ksh93/bltins/whence.c:
- Remove faulty extra check for undefined (= autoload) functions.
  This was already handled earlier, on lines 192-193.

src/cmd/ksh93/tests/builtins.sh:
- Add regression test.
- For previous 'whence -a' test, don't bother with shell function.

Fixes https://github.com/ksh93/ksh/issues/26
