Name packages by their module path in 15 manifests (issue 1966)

Kind: short package names (builds, sshkeys, forgemsg, backupgood,
diskreadings, grantsstate, busgrants) in `packages`, which the indexer's
judge refuses by design 32's rule (a Go package is named by its go.mod's
module path). This held mesh-delivery-gate, the build modules, mounts and
restic. Each key is now the import path the module's code uses, with its
series kept; the manifest tests read the new keys, and the host/machine-name
word tests in mounts, nfs-server, mesh-build-node and mesh-delivery-gate
look past the path's `git.novox.be/novox/` prefix.

Quick fix: only the gate's manifest. Thorough fix (chosen): all 15, since
the same refusal holds each. Follow-up for the checker: the candidate
verdict lets such a name through (J7(3)), so the merge check did not stop it.
