fix(ci): Handle gunzip trailing garbage warning in VM build

Browse Source 
OpenWrt firmware images contain trailing data that gunzip reports
as "trailing garbage" with exit code 2. This is normal and the
extracted image is valid. The fix ignores the warning while still
checking that extraction produced output.
