[Piglit] [PATCH 3/4] gen_const_builtin_equal_tests: Make it possible to autogenerate tests.

[Kenneth Graunke]

This changes the (unused) generator to output to

   generated_tests/spec/glsl-1.20/execution/built-in-functions

rather than the current directory.  Also, make sure the destination
directory exists.

Since the tests won't live in tests/shaders, they can't refer to
glsl-mvp.vert by name.  Just use gl_Position = gl_Vertex, since it's
a non-orthographic projection anyway.

Ths does change the VS in the tests slightly, but it's the right change,
and they pass before/after.
