Add fallback for debug upload

[EvilOlaf]

Description

For the unlikely case do some unneeded work and add a fallback JUST IN CASE ix.io is unreachable or down or closes door or doomsday is coming.

Jira reference number AR-625

How Has This Been Tested?

Tested with OPi Zero on 22.08

• [x] Do normal armbianmonitor -u and verify working
• [x] Block ix.io using iptables and retry to verify working fallback

• Duplicate IP censoring needs to be fixed (cosmetics). Maybe create a censored version of CollectSupportInfo and then parse it to the chosen upload target?
• Cascaded if statements could be made nicer? (cosmetics)

Fixed another small bug that was around since years. Also what if we twist the logic an use ours as default?

[EvilOlaf]

Funny. Bug had the same idea. As for myself I don't care or if I had to decide I'd leave ix.io since it proven stable over years now.

This is just another small step to promote "armbian" and costs us close to nothing.
