feat(audit): capture IPMI FRU/Elabel, mc info and LAN on every audit

The techdump — the only place the IPMI FRU / Elabel identity (Product Name
= server model, serials, part numbers) is recorded — only ran under LiveCD.
Run it on every audit so `bee audit` on an installed host captures it too.

Also add `ipmitool mc info` and `ipmitool lan print` to the techdump, and
pin `ipmitool fru print 0` to FRU device 0 to match the Export Tools
"FRU / Elabel" editor exactly.
