Fix build on some systems after #75.
On some platforms (but not all, including the one I tested this on) we
now get:
src/decodetable.cc:29:7: error: call to
constructor of 'std::unique_ptr<VCDiffCodeTableData>' is ambiguous

Just use the default ctor, which initializes both auto_ptr and
unique_ptr to null.
