[pve-devel] [PATCH manager] fix #3629: ui: rng: increase default ratelimit to 2048 B/s

FreeBSD 13 VMs will bug out and consume loads of idle CPU time if the
ratelimit is 1024 B/s or lower. Increasing to 2048 fixes the issue,
confirmed experimentally, and doesn't seem much worse as a default.

On the one hand this *really* sounds like a FreeBSD bug to me, even reading
through their bugtracker linked from the report in ours.

But on the other, 2048 doesn't sound much worse as a limit either, and since
this appears to be a rather new bug I think it's enough to change it in the GUI
and avoid any hassle with API default changes.

An "ostype" for BSDs might be nice too I suppose. Not sure "Other" would cover
this, I personally use "Linux" for my BSD VMs...
