linux-x86: Add GL-releated runtime libraries

This patch adds various libraries needed by libGL.so to our 32-bit
sysroot used to build SDK binaries. These are needed to build various
unit tests of our OpenGL HW emulation.

NOTE: These runtime libraries are only needed because we
      directly link -lGL to our test executables, and the linker
      refuses to do it if it doesn't find all libGL.so dependencies.

      These libraries are _not_ needed to run the final executable.

      As long as a working libGL.so is installed on the host system,
      the program should run just fine.

These libraries are taken from Ubuntu packages, and are MIT-style
licensed. For example, see:
