netlist_simulator_controller: fix build with gcc 13

[risicle]

Without this we get

In file included from /build/source/plugins/simulator/netlist_simulator_controller/include/netlist_simulator_controller/saleae_file.h:33,
                 from /build/source/plugins/simulator/netlist_simulator_controller/src/saleae_file.cpp:5:
/build/source/plugins/simulator/netlist_simulator_controller/include/netlist_simulator_controller/saleae_directory.h:79:9: error: 'uint64_t' does not name a type
   79 |         uint64_t mBeginTime;
      |         ^~~~~~~~

when building the NixOS package now we've switched to gcc 13
