base_image: fix locale warnings in custom images

Fix "cannot change locale" warnings during SSH connections by configuring
locales in the virt-builder template.

Changes:
- Add locales-all package for comprehensive locale support
- Configure locales during both image build (run-command) and first boot
  (firstboot-command) to handle both new and existing cached images
- Remove failing dpkg-reconfigure command

This ensures en_US.UTF-8 locale is available at boot, eliminating SSH warnings.
