[Piglit] [PATCH 2/4] tests/egl/egl-configless-context: Handle x-screen depth 30

[Mario Kleiner]

At X-Screen color depth 30, ARGB2101010 visuals get exposed
by capable GL implementations, instead of ARGB8888, so also
handle those in the depth 32 test case, by asking for an
alpha channel of >= 1 bit, instead of >= 8 bit.
