bug#52831: [installer] Locale problems with nss-certs

[Leo Famulari]

While testing the Guix System installer, I noticed that installation of
nss-certs has some problems that seem related to locales.

Some of the certificate's filenames are encoded in a way that isn't
supported by the environment in which they are being handled, and so
these certificates are not installed into the new system.

I've attached a screenshot of the error messages in the installer. The
problematic certificates are listed there.
