This reverts commit eb9e4e7a6c, see the note in
the original description of
<https://bugs.documentfoundation.org/show_bug.cgi?id=143148#c0> "Use pragma once
instead of include guards (Episode 2: Endgame)": "There are some source files
containing include guards that are meant to also be processed by compilers other
than LO's build baseline compilers: All URE include files [...] For those
source files, it is probably better to conservatively stick with include guards
than to replace them with #pragma once."
