hush shell: Avoid string write overflow when entering max cmd length
console_buffer array is defined to be CONFIG_SYS_CBSIZE + 1 long, whereas the_command array only CONFIG_SYS_CBSIZE long. Subsequent use of strcpy(the_command, console_buffer) will write final \0 terminating byte outside the_command array when entering a command of max length.
