installer: Use 'glibc-supported-locales'.

The list of locales supported by glibc is now built from source.

* gnu/installer/locale.scm (locale-string->locale): Add optional
'codeset' parameter and honor it.
(supported-locales->locales): Rewrite to 'read' from SUPPORTED-LOCALES.
* gnu/installer.scm (compute-locale-step): Pass the result of
'glibc-supported-locales' instead of the "aux-files/SUPPORTED" file.
* gnu/installer/aux-files/SUPPORTED: Remove.
* gnu/local.mk (dist_installer_DATA): Remove it.
