ddns-scripts: remove rework of OVH provider

This rework was unneeded, rather the fix in
https://github.com/openwrt/packages/pull/28174 is required to resolve
missing HTTP_AUTH support.

The original issue in https://github.com/openwrt/packages/issues/27526
(unable to update OVH DynHost IP address) was wrongly attributed to a
change on the OVH API. As discussed in
https://github.com/openwrt/packages/issues/28172 the API continues to
work for 24.10.5 system, as well as users using wget-ssl.

The changes in https://github.com/openwrt/packages/pull/27561 and
the followup fix https://github.com/openwrt/packages/pull/27694 add
unnecessary dependencies which are heavier than the actually needed
minimum.

Therefore return the OVH provider to the previous state, and let
https://github.com/openwrt/packages/pull/28174 resolved the issue.
