init/main.c: Remove redundant space from saved_command_line

There is a space at the end of extra_init_args. In the current logic, copying extra_init_args to saved_command_line will cause extra spaces in saved_command_line here or there. Remove the trailing space from extra_init_args to make the string in saved_command_line look more perfect.
