Lasse Collin 646032e3b0 XZ decompressor: Fix decoding of empty LZMA2 streams
The old code considered valid empty LZMA2 streams to be corrupt.
Note that a typical empty .xz file has no LZMA2 data at all,
and thus most .xz files having no uncompressed data are handled
correctly even without this fix.
