repo-add : fix package variables declaration

- arch was missing

- backup is not used by repo-add. However makepkg still needs to put it in
  PKGINFO because pacman uses it

- startdir is no longer used after the new delta implementation

- the declaration of group, depend, backup, etc is not needed because these
  variables are always declared before being used :
	declare $var="$val"
	case "$var" in
		group)    _groups="$_groups$group\n" ;;

- reorder the variables declaration to follow the same order than they are
  written to the depends and desc file, for making future checks easier
