libpayload: Fix build when both USB and PS/2 keyboard support is disabled

libpayload uses -Werror for some reason right now, and the
variable 'c' in curses_getchar is only used if CONFIG_USB_HID
or CONFIG_PC_KEYBOARD is defined, giving an unused variable
warning that gets promoted to an error.
So wrap the variable declaration around appropriate #ifdef's
