[dvipdfmx] Intermittent xdvipdfmx failure

[Shunsaku Hirata]

Thank you for trying.

A random 6 bytes tag is prepended to the font name when a
font is embedded as a font subset which can lead to different
results (even in data size) when data is compressed.

I think this is the reason. Probably data size is always the same
if compression is turned off.

Thanks,
Shunsaku Hirata
