readutmp: Fix naming of configure option

The configure option '--enable-systemd' is a misnomer, as can be seen from
the GNU Coding Standards
  https://www.gnu.org/prep/standards/html_node/Configuration.html
and from the Autoconf manual
  https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.73/html_node/Optional-Features.html
  https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.73/html_node/Package-Options.html
  https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.73/html_node/External-Software.html

This patch renames it to '--with-systemd'.

Pàdraig, find attached a proposed patch for coreutils, accordingly.
