Merlin timezone fix does not work with recent firmware (asd deletes folder/files)

[pro-sumer]

Context

• CLI Version: 1.45.0
• Platform: ASUSWRT-Merlin 3006.102.4_0

The NextDNS CLI creates a folder zoneinfo in /jffs and downloads a timezone file into that.

However, recent ASUSWRT(-Merlin) firmwares seem to have an anti-malware tool asd that deletes the folder immediately after it is created (same happens to the file download, when I try the curl command manually in an existing folder).

This leaves my router in a state where NextDNS breaks my /etc/localtime and is thus showing the wrong time.

Suggestions:

1. Don't overwrite /etc/localtime if the user has set it
2. Check whether this 6 years old fix is still needed
3. Provide a new/better fix
