Ensure, that Tramp uses GNU style emulation when calling ls-lisp

* lisp/net/tramp-sh.el (tramp-sh-handle-insert-directory): Reorganize.

* lisp/net/tramp.el (ls-lisp-dirs-first, ls-lisp-emulation)
(ls-lisp-ignore-case, ls-lisp-verbosity): Declare.
(tramp-handle-insert-directory): Bind `ls-lisp-*' options.  Call
`ls-lisp-set-options'.
