Initialize variables correctly

1) gmirror.inc: there are two calls to exec(), those calls expect the 2nd parameter to be an array, this commit initializes the variables correctly. 2) system.php: variable dnslist is used as an array without prior type initialization. This is one of the causes for apparent PR #2680 problems (which led to its reversal). Note: After this commit is merged PR #2680 may be safely reapplied for more tough code.
