tdf#116102 Revert "tdf#109080 First page header/footer ODF (2/2)"

Revert this on the libreoffice-6-0 branch; the patch to import the
element by its new name was only added in LO 5.3.6, so
probably 2 release cycles is too short for a change like this.

This revert delays the change until LO 6.1.

This reverts commit f1481007.
