Cairo tests fail on 32-bit Appveyor
Apparently have been broken for 9 months https://ci.appveyor.com/project/nalimilan/bindeps-jl/build/1.0.222
The first failure was on #300: that doesn't seem related, so it was probably a change with Cairo.jl (which doesn't have 32-bit tests enabled).
Either we should fix Cairo.jl, or remove it from the tests.
Looks like some gcc issue: https://github.com/JuliaGraphics/Cairo.jl/pull/196
The easiest option at this stage is to move Cairo to binaryprovider.jl, and get rid of the test here.
The point of the test is to exercise code paths here, so if the upstream package changes to no longer use BinDeps then the test dependency should be upper-bounded. Cairo can probably be skipped on win32 for now but it should be replaced by a different WinRPM-using package that does work.
