cli7zplugin: fix incompatibility with original 7-Zip
Fixup for !90 (merged)
The issue: !90 (comment 471577) / https://bugs.kde.org/show_bug.cgi?id=456797
Yes, turns out it is that simple. I don't know why original code expects strictly z here, the letter can be different and depends on 7-Zip build type.
