package/gvfs: fix CVE-2019-3827
An incorrect permission check in the admin backend in gvfs before
version 1.39.4 was found that allows reading and modify arbitrary files
by privileged users without asking for password when no authentication
agent is running. This vulnerability can be exploited by malicious
programs running under privileges of users belonging to the wheel group
to further escalate its privileges by modifying system files without
user's knowledge. Successful exploitation requires uncommon system
configuration.
