Subject: [PATCH] Disable the seccomp sandbox
References: boo#1174448
In the referenced bug, it somehow fails to make the created context current,
so no GL vendor detection is performed and it is assumed to not be Nvidia
or on Wayland. This breaks rendering.
While it would be enough to only disable the sandbox in this particular case,
it's planned to drop sandboxing anyway
(https://invent.kde.org/plasma/kscreenlocker/-/merge_requests/9) so just do the
same here, just in a simpler way with less side effects.
