            Log:
            Re-enable a workaround to fix g-i-s/gnome-keyring (#2005625)

This re-enables a workaround which upstream recently disabled
for security reasons, but which is still currently needed for
gnome-keyring to function properly during gnome-initial-setup.
This should fix several bugs that were all consequences of
gnome-keyring not working correctly:

+Subject: [PATCH] Re-do "gdbus: Use DBUS_SESSION_BUS_ADDRESS if AT_SECURE but
+ not setuid""
+
+This reverts commit 0f9c7ed0219cc182a183ba78245f3b461fd664e6,
+which reverted commit 7aa0580cc559148e0f4646461a42102bd98228b6,
+so we go back to allowing this workaround. gnome-keyring still
+needs it to work correctly during gnome-initial-setup on Fedora,
+and when it doesn't work correctly, there are several major
+consequences:
