sys/usb_board_reset: add dummy reset in bootloader function

Browse Source 
Definition of a function as weak symbol for reset in bootloader which prints an error message if no real implementation is compiled in and
the module `riotboot_reset` is not used. This is required if the module `usb_board_reset` is used to restart the board with an application via an USB CDC ACM interface, but the board's bootloader does not support a reset in the bootloader.
