Installation of IPFS on RPI

[mitra42]

I had some issues with getting IPFS to work on RPI/IIAB, just touching back into this.

Generic IPFS task is at https://github.com/internetarchive/dweb-mirror/issues/22

Steps:

• [x] Upgrade yarn for dweb-mirror
• [x] Try dweb-mirror/install_ipfs and remind myself where issue was
• [x] fix issues on install_ipfs (was problem with 1 v l in name of processor)
• [ ] BLOCKED on dist.ipfs.io reliability issues :-( see https://github.com/ipfs/ipfs-update/issues/105

Cleanup when done ...

• [ ] Review #22 again,
• [ ] figure out auto-start/stop
• [ ] Think about how to give user choice of installing (probably not by default, given IPFS is a CPU / bandwidth hog)
• [ ] Do default install of IIABv7 and see if works with (presumably) edited install_ipfs.sh
