(ok 2.9.2) Unzip encrypt detection bug

if flags (GPF) <> 0 in ZIP, raising error 'encrypt not
supported'.

lines 280-281 of unzip.lib.php contains that code:
----------------------------------
// Check if data is encrypted
$bE = ($aP['GPF'] && 0x0001) ? TRUE : FALSE;
----------------------------------

I think, instead of '&&' must be '&', else if flags
(GPF) <> 0, raising error 'encrypt not supported';
