Subtracts the VGA framebuffer constant (4 MiB) from the value of 
build_start_mem passed into the HVM domain builder, in the same way that we 
already subtract this constant from the value of build_max_mem. This allows us 
to satisfy the domain builder contract which expects that (build_start_mem <= 
build_max_mem) and for both memory values to *not* include framebuffer memory.
