    riemann: Fix bug found by MSVC203 Code Analysis

    The following doesn't quite do what it might seem to be doing:
        guint64 num;
        guint8 b;
        num |= ((b & 0x7f) << shift);

    The warning from MSVC2013:
     Arithmetic overflow:  32-bit value is shifted, then cast to 64-bit
      value. Results might not be an expected value
