init/bootconfig: pass init arguments in documented order

Browse Source 
start_kernel() appends command-line init arguments before
bootconfig init arguments, while setup_command_line()
places them in the opposite order. As a result, the
arguments passed to init do not match the saved command
line, reversing the intended precedence of options.

Parse extra_init_args before after_dashes so command-line
init arguments are passed last.
