Add tzdata as depedency of the Nix package Nix + libc has fundamental design flaw on TZ loading: <https://github.com./NixOS/nixpkgs/issues/65415> Glibc looks "<its own store>/share/zoneinfo" on TZ lookup, and as it itself does not contain timezone data, every timezone functionality will be broken by treating every timezone as UTC. This won't be a problem on NixOS as it sets $TZDIR environment variable. However, non-NixOS system without $TZDIR faces this problem. For this reason, every program uses libc datetime function must declare tzdata dependency.
