multi-bind tests use multisampled images without checking for support

Some tests sample/store from GL_TEXTURE_2D_MULTISAMPLE{_ARRAY} without
checking the value of GL_MAX_IMAGE_SAMPLES, which can be zero. Skip,
these targets in the driver reports 0, meaning that it can't do
multisample load/store image operations.
