Exclude some tests in Windows RDP session

It seems that RDP may change (limit?) color space (even configured
to use 32-bit colors), and then some tests start failing like this:

Test name: BackendTest::testDrawAlphaBitmapMirrored
equality assertion failed
- Expected: c[80000000]
- Actual  : c[84000000]

Debugging ImplDrawBitmap in vcl/win/gdi/gdiimpl.cxx, and adding a
call to GetPixel immediately after the call to StretchDIBits, shows
that the resulting color on the device is different from the color
in the bitmap data: e.g., for original color {128, 0, 0} the result
is {132, 0, 0}.

Calling GetColorAdjustment shows that there's no color adjustments
set for the device, so I can't detect or modify the behavior this
way. So just disable the tests for now when running in RDP sessions.
