[Piglit] [PATCH 2/2] teximage-errors: fix a couple mistakes, add two new test cases

[Brian Paul]

From: Brian Paul <brianp at vmware.com>

Fix incorrect texture height (16, not 15).
Fix incorrect width, height for glCopyTexSubImage2D() test.
Add two new SubImage tests for non-existant mipmap levels.
