Add JVM support to Flatpak

...fixing <https://github.com/flathub/org.libreoffice.LibreOffice/issues/5>
"Add JRE-based components".

It appeared to be easiest to install the Ant build-time dependency to
/run/build/libreoffice/ant, instead of making it into a flatpak-builder module
of its own.  (The sha512 is as given at
<http://ant.apache.org/bindownload.cgi>.)

To avoid further dependencies, configure --without-export-validation and
--without-junit, only affecting build-time checks (and the amount of checks thus
affected by a plain `make` should be small).
