Force cube map texture complete on Linux AMD

CopyTex{Sub}Image2D reports INVALID_OPERATION error if the destination
texture is an integer incomplete cube map texture on Linux AMD. Similarly,
TexSubImage2D reports OUT_OF_MEMORY error if the destination texture is a
srgb incomplete cube map texture on Linux AMD. This is a bug in AMD Linux
driver. This CL workarounds this bug by forcing the texture to be cube map
complete.

These tests still fail:

From https://build.chromium.org/p/chromium.gpu.fyi/builders/Linux%20Release%20%28AMD%20R7%20240%29/builds/2007 to 2036 (last one as I write this) these fail consistently:

WebglConformance_conformance2_textures_canvas_tex_2d_rgb8ui_rgb_integer_unsigned_byte

WebglConformance_conformance2_textures_webgl_canvas_tex_2d_rgba8ui_rgba_integer_unsigned_byte

these fail sporadically (though every time one of them fails):

WebglConformance_conformance2_textures_image_data_tex_3d_srgb8_alpha8_rgba_unsigned_byte
WebglConformance_conformance2_textures_image_data_tex_3d_srgb8_rgb_unsigned_byte
WebglConformance_conformance2_textures_image_tex_2d_r11f_g11f_b10f_rgb_float

and the remainder pass.

To Comment 6,
The consistent failures in Comment 6 is caused by a Linux AMD bug, see  bug 712117 . 
Per https://codereview.chromium.org/2821913002/#msg25, we could not workaround the whole bug.
