	* default.exp: Add support for setting SUPPORT_DESMD5 flag on the
	TGT principal.  Add test pass des.md5-tgt for exercising enctype
	similarity inconsistency.  Add test pass des.no-kdc-md5 for
	exercising failure to constrain session key issuance to
	permitted_enctypes.  Pepper the code with null calls to
	expect_after to prevent misfiring of expect_after clauses.
	(setup_srvtab): Look for some possible error cases to avoid timing
	out.
	(setup_root_shell): Restore timeout so we don't wait 5 minutes in
	other places.
