    xen/link: Include .debug_str_offsets in DWARF2_DEBUG_SECTIONS
    
    Building Xen with Clang-17 yields the following warning:
    
      ld: warning: orphan section `.debug_str_offsets' from `prelink.o' being 
placed in section `.debug_str_offsets'
      ld: ./.xen.efi.0xffff82d040000000.0:/4: section below image base
      ld: ./.xen.efi.0xffff82d040000000.1:/4: section below image base
      ld: warning: orphan section `.debug_str_offsets' from `prelink.o' being 
placed in section `.debug_str_offsets'
      ld: xen.efi:/4: section below image base
    
    Set the alignment to 4 as it holds 4-byte values, despite the fact that 
Clang
    appears to only use 1.
