i965: Make calculate_attr_overrides return the URB read offset.
Traditionally, we've hardcoded "URB Entry Read Offset" to 1 (which
represents 2 vec4 varying slots) to skip over the 8 DWord VUE header.
In order to support ARB_fragment_layer_viewport, we'll need to read
from that header. This patch adds the basic plumbing necessary to
calculate a value dynamically and hook it up in the SBE packets.
