fuzz: Fix warnings for unused arch code

Browse Source 
Under the fuzzer this code appears dead:

error: field `0` is never read
   --> /home/rob/src/cloud-hypervisor/arch/src/x86_64/mod.rs:128:32
    |
128 | struct MemmapTableEntryWrapper(hvm_memmap_table_entry);
    |        ----------------------- ^^^^^^^^^^^^^^^^^^^^^^
    |        |
    |        field in this struct
    |
    = note: `MemmapTableEntryWrapper` has a derived impl for the trait `Clone`, but this is intentionally ignored during dead code analysis
    = note: `-D dead-code` implied by `-D warnings`
    = help: to override `-D warnings` add `#[allow(dead_code)]`
help: consider changing the field to be of unit type to suppress this warning while preserving the field numbering, or remove the field
