[Piglit] [PATCH 7/8] OES_compressed_ETC1_RGB8_texture-basic: fix glCopyTexImage2D error check

[Daniel Kurtz]

According to OpenGL ES 1.1 [0] and  OpenGL ES 2.0 [1], for
glCopyTexImage2D:

GL_INVALID_ENUM is generated if internalformat is not an accepted constant.

[0] http://www.khronos.org/opengles/sdk/1.1/docs/man/glCopyTexImage2D.xml
[1] http://www.khronos.org/opengles/sdk/docs/man/xhtml/glCopyTexImage2D.xml

Note: This is *different* than OpenGL [2] and OpenGL ES 3.0 [3], which
both specify:
GL_INVALID_VALUE is generated if internalformat is not an accepted format.

[3] http://www.khronos.org/opengles/sdk/docs/man3/xhtml/glCopyTexImage2D.xml
