nit: s/tests/kTestStrings or so

nit: I'd ifdef out the whole test thingie and put a comment that only on Android
we attempt to get the driver version from the GL_VERSION string.

+    {"Adreno (TM) 320", "Qualcomm", "OpenGL ES 2.0 V@14.0 AU@04.02 (CL@3206)",
+     "14.0"},
+    {"Adreno (TM) 420", "Qualcomm", "OpenGL ES 3.0 V@84.0 AU@ (CL@)", "84.0"},
+    {"PowerVR Rogue G6430", "Imagination Technologies",
+     "OpenGL ES 3.1 build 1.4@3283119", "1.4"},
+    {"Mali-T604", "ARM", "OpenGL ES 3.1", "0"},

Can you also update the comment in gpu_info_collector_android.cc since it
doesn't apply anymore?

  // Extract driver version from the second number in a string like:
  // "OpenGL ES 2.0 V@6.0 AU@ (CL@2946718)"

Maybe just say that it tries to find a version number behind the 'OpenGL ES x.x'
string?

+    {"NVIDIA Tegra 3", "NVIDIA Corporation", "OpenGL ES 2.0 14.01003",
+     "14.01003"},
