libunwind: Fixed lzma build error

If xz is present libunwind enables support for LZMA-compressed symbol
tables which results in unresolved lzma symbol linker errors. This error
has been fixed in latest libunwind git. For now, until next libunwind
release, we simply disable LZMA-compressed symbol tables.
