  [ELF] Refine warning condition for memory region assignment for non-allocatable section

The warning "ignoring memory region assignment for non-allocatable section"  should be generated under the following conditions:

* sections without SHF_ALLOC attribute and,
* presence of input sections or data commands (ByteCommand)

The goal of the change is to reduce spurious warnings that are generated for some output sections that have no input section.
