Disable t0110's high-bit test on Windows

The bash Git for Windows uses (i.e. the MSys bash) cannot pass
command-line arguments with high bits set verbatim to non-MSys programs,
but instead converts those characters with high bits set to their hex
representation.

For example, when running

	strings "$(echo -e '\x80')"

(where strings.exe is a MinGW program, not an MSys one) it will complain
about not finding the file called "80".
