cloudflare-dyndns: 5.3 -> 5.4

Changelog available at [^1]. The most important fix is the issue where
it fails to read API token from a file if it ends with a newline. This
is particularly important since cloudflare-dyndns now reads services.
cloudflare-dyndns.apiTokenFile directly.

The list of fixes is small, making it suitable to be backported to NixOS
25.05.
