svga: Adjust alpha for S3TC_DXT1_EXT RGB formats

According to spec, S3TC_DXT1_EXT RGB formats are supposed to be
opaque. Correspoding svga formats are not handling it so explicitly
setting it to 1.0.
This fixes piglit test spec@ext_texture_compression_s3tc@s3tc-targeted
Note: This test is testcase for freedesktop bug 100925

Tested with mtt-piglit and mtt-glretrace on 8,9,10,11 and 15
