fix: migrate runtime base images from distroless/minimal to distroless/base

Go 1.26 enforces FIPS-compliant system crypto, which requires crypto
libraries to be present at runtime. distroless/minimal lacks these
libraries and will cause pod startup failures.

This change migrates all runtime base images to distroless/base:3.0,
which includes the required crypto libraries while remaining minimal.

Changes:
- build/images.mk: MARINER_DISTROLESS_IMG minimal → base
- bpf-prog/ipv6-hp-bpf/linux.Dockerfile: cbl-mariner/distroless/minimal:2.0 → azurelinux/distroless/base:3.0
- .pipelines/build/dockerfiles/ipv6-hp-bpf.Dockerfile: minimal → base
- Regenerated all template Dockerfiles via make dockerfiles

Resolves #4364
