util/tracing: switch to semconv v0.21.0

Align the package to use the same version of semconv we use elsewhere. Worth
noting that some modules still use v0.17;

- go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc
- go.opentelemetry.io/contrib/instrumentation/net/http/httptrace/otelhttptrace
- go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp

Git grep on buildkit;
