vc4: Enable nir_lower_io for uniforms

Altough the driver isn't expected to receive nir_var_uniform types
from GLSL this happens currently for one of the internal driver shaders.

At vc4_get_yuv_fs at vc4_blit.c there is a "stride" nir_var_uniform
variable that needs to be lowered so the shader can be compiled.

This regression was affecting several piglit tests under
spec/ext_image_dma_buf_import and at least MythTV application.
