Remove D-Bus tests from Vala build on Windows
@astavale
Submitted by Al Thomas Link to original bug (#767729)
Description
tests/dbus/filedescriptor.test includes calls to the Unix only UnixInputStream. This causes 'make check' when building Vala on Windows to fail - see https://bugzilla.gnome.org/show_bug.cgi?id=761307
It appears there is a Windows port of D-Bus: https://www.freedesktop.org/wiki/Software/dbus/#index6h1 although I can't find it in the MSYS2 repository.
