build: Fix beta clippy issue (derive_partial_eq_without_eq)

warning: you are deriving `PartialEq` and can implement `Eq`
  --> vmm/src/serial_manager.rs:59:30

59 | #[derive(Debug, Clone, Copy, PartialEq)]
   |                              ^^^^^^^^^ help: consider deriving `Eq` as well: `PartialEq, Eq`
