[BusyBox] gunzip -t always return zero on broken .gz

[SHOJI Yasushi]

Hi all,

gunzip in busybox-stable doesn't return non zero even if the testing
archive is broken.

GNU gunzip and busybox unstable returns 1 at least on my box (debian
sid)

i'm attaching a patch anyway. it's against current busybox.stable cvs.

tia,
