mesa: Set the "Integer" field of gl_client_array properly.

This patch ensures that gl_client_array::Integer is properly set to
GL_TRUE for vertex attributes specified using glVertexAttribIPointer,
and to GL_FALSE for vertex attributes specified using
glVertexAttribPointer, so that the vertex attributes can be
interpreted properly by driver back-ends.
