src/optparse.lisp: Simplify `set-command-line-arguments'.

If we depend on `cl-launch' and assume that we're always started through
it then we don't need to do such complicated things to put together the
command line.

It's not all happy bunnies, unfortunately, because we have to mess with
system-specific details to discover the program name from a dumped
executable image.
