d/lintian-overrids: add repeated-trigger-name override

in this package we provide api functions, thus we want to activate
the pve-api-update trigger, so that packages like pve-manager get
notified about it. But we also use api functions directly so we setup
an interest in the pve-api-update trigger. This results in an lintian
error (lintian version from buster or newer) which we can override:

> [...]
> This tag is also triggered if the package has an activate trigger
> for something on which it also declares an interest. The only (but
> rather unlikely) reason to do this is if another package also
> declares an interest and this package needs to activate that other
> package. If the package is using it for this exact purpose, then
> please use a Lintian override to state this.
