[dvipdfmx] silencing mktexpk

[Shunsaku Hirata]

Thanks for the suggestion.

I decided to place the suggested code for suppressing kpathsea
error messages after the second pass (after processing
dvipdfmx:config specials), although currently the "q" option does
not take effect in the config special (this might be changed).

Thanks,
Shunsaku Hirata
