auth: declare enable-lua-record-updates unconditionally

The Lua record update restrictions added in #17131 rely on the
enable-lua-record-updates setting. When built without Lua record support,
this setting is not defined, causing errors like:

Undefined but needed argument: 'enable-lua-record-updates'

Add the setting unconditionally.
