Fix testcases to call tst_exit() on exit

Fix all testcases that does not propagate test result from the main().

This patch was created with following coccinelle sematic patch:

@@ expression E;@@
setup()
...
- return E;
+ tst_exit();

(which basically says to replace all return statements that follow call
 to setup() with tst_exit())
