Change param of AOME_SET_SPATIAL_LAYER_ID to int

Change the parameter type of AOME_SET_SPATIAL_LAYER_ID from unsigned int
to int. This change is binary compatible because the valid spatial layer
id values 0..3 can be represented in either the unsigned int or int
type. libaom uses the int type for spatial layer ids internally and in
other related API items such as AOME_SET_NUMBER_SPATIAL_LAYERS and
aom_svc_layer_id_t. So this CL makes the API more consistent.
