block: vhdx: use C ABI-qualification for packed structures

Browse source 
This fixes the following issue from beta Clippy:

error: item uses `packed` representation without ABI-qualification
Error:    --> block/src/vhdx/vhdx_header.rs:333:1
    |
331 |   #[repr(packed)]
    |          ------ `packed` representation set here
332 |   #[derive(Clone, Copy, Debug)]
333 | / pub struct RegionTableEntry {
334 | |     pub guid: Uuid,
335 | |     pub file_offset: u64,
336 | |     pub length: u32,
337 | |     pub required: u32,
338 | | }
    | |_^

    = warning: unqualified `#[repr(packed)]` defaults to `#[repr(Rust, packed)]`, which has no stable ABI
    = help: qualify the desired ABI explicity via `#[repr(C, packed)]` or `#[repr(Rust, packed)]`
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#repr_packed_without_abi
