usbguard-notifier: fix build against `gcc-13`

Without the change `usbguard-notifier` fails the build on `staging-next`
as:

In file included from src/Notifier.hpp:24,
from src/Main.cpp:21:
src/Serializer.hpp:35:5: error: 'uint32_t' does not name a type
35 | uint32_t device_id;
| ^~~~~~~~
src/Serializer.hpp:25:1: note: 'uint32_t' is defined in header '<cstdint>'; did you forget to '#include <cstdint>'?
