Bug#992474: override: bind9-libs:libs/optional

[Daniel Lewart <lewart3@gmail.com>]

FTP Team,

bind9-libs is libs/standard.

Debian Policy 2.5 Priorities says:
    In particular, this means that C-like libraries will almost never
    have a priority above optional, since they do not provide
    functionality directly to users.

Also, discussed here:
    https://lists.debian.org/debian-devel/2021/07/msg00046.html
    https://lists.debian.org/debian-devel/2021/07/msg00048.html

Please change bind9-libs to:
    libs/optional

Thank you!
