[9.0] (backport #9732) chore: fix formatting issues in logp printf-style calls

[mergify]

Proposed commit message

This PR fixes fatal go vet errors on calls to logp functions. Release v0.22.1 of elastic-agent-libs enabled proper go vet support for printf style calls in logp, and that uncovered many misuses of printing directives.
