mesa: Use a single enable for GL_EXT_texture_array and GL_MESA_texture_array

Every driver that enables one also enables the other.  The difference
between the two is MESA adds support for fixed-function and assembly
fragment shaders, but EXT only adds support for GLSL.  The MESA
extension was created back when Mesa did not support GLSL.
