xzdec: Remove unused short option -M

"xzdec -M123" exited with exit status 1 without printing
any messages. The "M:" entry should have been removed when
the memory usage limiter support was removed from xzdec.

Fixes: 792331bdee706aa852a78b171040ebf814c6f3ae
Closes: https://github.com/tukaani-project/xz/pull/143
