devconfig: fix locale configuration on existing VMs

Add locale configuration tasks to firstconfig to ensure existing VMs
have correct locales, complementing the base image template fixes.

This ensures en_US.UTF-8 locale is properly configured on:
- New VMs: fixed during image creation (virt-builder template)
- Existing VMs: fixed during firstconfig (this commit)

Changes:
- Install locales-all package if missing
- Configure /etc/default/locale and /etc/locale.gen files
- Generate and update locales with locale-gen and update-locale

Runs early with firstconfig tag for immediate fix during VM setup.
