[bug#30292] [PATCH] gnu: libreoffice: Fix build with Poppler >= 0.62.0.

[Leo Famulari <leo@famulari.name>]

I'll push this if and when the build finishes and I confirm that
LibreOffice is still working.

* gnu/packages/libreoffice.scm (libreoffice)[arguments]: Patch header and
function names in 'prepare-src' phase.
