Attempt to fix chromium builds

It would seem that `glslang_sources` has a private dependency on `glslang_build_info`, so `glslang_validator` cannot transitively `#include` the generated `glslang/build_info.h` header.

Add `glslang_build_info` as a direct dependency to `glslang_validator`.
Also remove the duplicate dependency on `glslang_build_info` in `glslang_sources_common`

Note: This is a speculative fix as I can build Chromium fine without these changes.
Not sure what's different between these configs.
