Vadim Zeitlin 9e4d51dfca Disable tests not working in ANSI build 
Most of them can't be expected to work, e.g. non-ASCII file names can't
be supported without Unicode support.

Some others, e.g. test for NULs in wxDataOutputStream, are questionable,
as it seems that it might be possible to fix them in ANSI build too, but
for now just do the simplest thing to make the tests pass on Travis.
