xz: Move suffix check after stdout mode is detected.
This fixes a bug introduced in cc5aa9ab138beeecaee5a1e81197591893ee9ca0 when the suffix check was initially moved. This caused a situation that previously worked: echo foo | xz -Fraw --lzma1 | wc -c to fail because the old code knew that this would write to standard out so a suffix was not needed.
