OCPBUGS-86882:[release-4.15] bump google.golang.org/grpc to v1.79.3

[AkashMore08]

Address CVE-2026-33186 via transitive dependency update

This PR resolves CVE-2026-33186 for release-4.15 by replacing google.golang.org/grpc with github.com/openshift-sustaining/grpc-go@v1.64.1-sec.1, a patched fork containing security fixes equivalent to upstream v1.79.3.

Along with the CVE fix, we had to manually bump go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc to v1.17.0.

Why otlptracegrpc was bumped to v1.17.0?

Replacing google.golang.org/grpc with v1.64.1-sec.1 changes the module graph the new grpc version requires higher minimum versions of shared dependencies (google.golang.org/protobuf v1.33.0, golang.org/x/net v0.26.0, etc.). This forces go mod tidy to re-resolve the entire dependency tree, which exposes a pre-existing broken module resolution in otlptracegrpc v1.10.0 through v1.16.0.

These versions depend on internal packages (go.opentelemetry.io/otel/exporters/otlp/internal, go.opentelemetry.io/otel/exporters/otlp/internal/envconfig) that were resolved via local replace directives within the OpenTelemetry monorepo during development. When consumed from the Go module proxy, those local replaces are ignored, and go mod tidy fails because the enclosing module (go.opentelemetry.io/otel/exporters/otlp@v0.20.1) does not contain these packages.

otlptracegrpc v1.17.0 is the first version that inlined these internal packages and removed the broken external module dependency. This bump then transitively upgrades otelgrpc (from v0.35.0 to v0.49.0), the core otel SDK, and other shared dependencies are auto-resolved by go mod tidy.
