Make all required directories when installing

When installing into a normal system, one can assume that target
directories, such as /usr/bin, already exists.  But when installing
into a subdirectory for the purpose of creating a package, one cannot
assume that all directories already exist.  Therefore, when
installing, we must not check if any directories exist, and must
instead always create any directories we want to install into.

* Makefile (confdir/mandos.conf, confdir/clients.conf, install-html):
  Use the "-D" option to "install" instead of creating the directory
  separately.
  (install-server): Move creation of $(CONFDIR) down to before it is
  needed.  Don't check if the $(TMPFILES) or $(SYSUSERS) directories
  exist; instead create them by using the "-D" option to "install".
  Create the $(PREFIX)/sbin directory.  Always use
  "--target-directory" if possible; i.e. if the file name is the same.
  Create the $(DBUSPOLICYDIR) and $(DESTDIR)/etc/init.d directories by
  using the "-D" option to "install".  Don't check if the $(SYSTEMD)
  directory exists; instead create it by using the "-D" option to
  "install".  Create the $(DESTDIR)/etc/default and $(MANDIR)/man8
  directories by using the "-D" option to "install".  Create the
  $(MANDIR)/man5 directories explicitly.
  (install-client-nokey): Remove unnecessary creation of the
  $(CONFDIR) directory.  Don't check if the $(SYSUSERS) directory
  exists; instead create it by using the "-D" option to "install".
  Move the "--directory" argument to be the first argument, for
  clarity.  Create the $(PREFIX)/sbin directory.  Use the "-D"
  argument to "install" when installing
  $(INITRAMFSTOOLS)/hooks/mandos,
  $(INITRAMFSTOOLS)/conf.d/mandos-conf,
  $(INITRAMFSTOOLS)/conf-hooks.d/zz-mandos,
  $(INITRAMFSTOOLS)/scripts/init-premount/mandos,
  $(INITRAMFSTOOLS)/scripts/local-premount/mandos,
  $(DRACUTMODULE)/ask-password-mandos.path, and
  $(DRACUTMODULE)/dracut-module/ask-password-mandos.service.  Create
  the $(MANDIR)/man8 directory.
