    Summary: Updated flatpak packages fix security vulnerabilities

    Details: Sandbox escape where a malicious application can execute code outside the sandbox by controlling the environment of the "flatpak run" command when spawning a sub-sandbox (CVE-2021-21261). A potential attack where a flatpak application could use custom formatted .desktop files to gain access to files on the host system (CVE-2021-21381). The update also removes the unnecessary flatpak-tests subpackage.
