[Piglit] [PATCH] arb_uniform_buffer_object-minmax: divide block size by 4 to get components

[Brian Paul]

GL_MAX_UNIFORM_BLOCK_SIZE is in bytes.  A "component" is regarded as being
four bytes in size.  So to compute the number of components, divide the
block size by 4.

With this change, nvidia's driver passes the test.
