mesa/main: consider multisampling enabled when number of samples == 1
There are some differences between how non-multisampled framebuffers (i.e.
samples == 0) and multisampled framebuffers with a single sample should be
treated. For example, alpha to coverage and writing to gl_SampleMask has an
effect with single-sample multisample framebuffers, but not on
non-multisample framebuffers.
This fixes GL45-CTS.sample_variables.mask.*.samples_1.* at least for
Gallium drivers (and possibly others, though at least radeonsi needs an
additional fix).
