feat: sealing: Allow overriding worker hostname

[magik6k]

Related Issues

This PR expands #7937 a bit

Proposed Changes

• Add a new config field to lotus-miner - Storage.LocalWorkerName
• Add a new flag/envvar to lotus-worker - --name/LOTUS_WORKER_NAME
• When set, use that name instead of the worker hostname in places where worker names are visible

TODO

• Write an itest
• Go through sealer code looking for missed os.Hostname calls
• Test manually
  • miner-builtin worker name
  • lotus-worker name
