Fix filter for getting build nodes

[JenySadadia]

Fix node state field in filter for getting build nodes from maestro.
Maestro sends all the build nodes to dashboard except running nodes.
Fix the filter accordingly.

[JenySadadia]

Tested validation after fixing the filter:

$ kci-dev --settings kci-dev.toml maestro  validate builds --all-checkouts --days 1
