pid: add missing override specifiers

[pid/controller.hpp:18] -> [pid/pidcontroller.hpp:28]: (style) The
function 'inputProc' overrides a function in a base class but is not
marked with a 'override' specifier.
[pid/controller.hpp:20] -> [pid/pidcontroller.hpp:30]: (style) The
function 'outputProc' overrides a function in a base class but is not
marked with a 'override' specifier.
[pid/controller.hpp:22] -> [pid/pidcontroller.hpp:32]: (style) The
function 'process' overrides a function in a base class but is not
marked with a 'override' specifier.
[pid/controller.hpp:24] -> [pid/pidcontroller.hpp:34]: (style) The
function 'getID' overrides a function in a base class but is not marked
with a 'override' specifier.
