bug#50830: [core-updates-frozen] glibc looks for $sysconfdir/etc/localtime rather than /etc/localtime

[John Kehayias via Bug reports for GNU Guix]

Just to followup, here is the relevant part of my `guix describe`:

  guix c6a8d6d
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: core-updates-frozen
    commit: c6a8d6db77520097bd0b2df99bfab659bfcfd64c

On a side note, nearly everything else seems to work well for me on 
core-updates-frozen. Will be happy to test a post-world-rebuild when that comes.
