Fixes a regression introduced in cc7fa592.
Reported by Tomas Cech <tcech@suse.cz>.

* guix/scripts/system.scm (install): Fix order of arguments to 'lift'
  and 'lift2'.

Appending to "raw" args broke optional parameters in 'guix package -I'

parsing each set of options on its own and append resulting alists
together afterwards.

  (parse-options) and add explicit argument.  New form of (parse-options)
  using its old algorithm via -from function.

* guix/scripts/package.scm: Ditto.
