mesa: Mark FBOs with compressed color attachments as FBO-incomplete.
Both EXT_fbo and ARB_fbo agree on this. Fixes a segfault in the metaops mipmap generation in Intel for SGIS_generate_mipmap of S3TC textures in Regnum Online. Bug #21654. (cherry picked from commit 0307e609aa3e707eeb40051bd664d36f2340ba9b)
