Fix stefankoelle build: temporarily hide .eleventyignore

build-pdf.sh now temporarily renames .eleventyignore during the
stefankoelle Eleventy build, restored via trap on EXIT. This allows
the standalone stefankoelle build to work while the main build
still ignores stefankoelle/ via .eleventyignore.
