[Piglit] [PATCH 3/4] util: Request minimal alpha channel in chooose_config_attribs().

[Mario Kleiner]

Only require a 1 bit alpha channel, so tests work on
both RGBA 8/8/8/8 and RGBA 10/10/10/2 configurations.

Note that this will cause many tests not to be skipped,
which assume an 8 bit alpha channel instead of a 2 bit
alpha channel. These tests instead fail in RGBA1010102
config.
