Fix some minor issues in advancemame compilation. (#64)

* advance/dos/wss.c: get_played_sample_count() was missing parentheses, causing
    the function address to be compared instead of the return value.
* advance/svgalib/svgalib.c: memset argument order was incorrect, causing the
    structure to be uninitialized instead
* src/machine/eeprom.c: indent order of debug print triggered a spurious warning
    about "if" guarding
