obmc-phosphor-image: Don't install any locales

Don't install any locales in an obmc-phosphor-image.  The defaults
probably meet most requirements at present and this saves ~128K with an
xz compressed squashfs.

Remove locale setting from distro configuration.  The defaults are fine
and this also allows the user to override.
