[PATCH ifupdown2 1/4] nlcache: Fix missing nodad option in addr_add_dry_run

[Robin Christ <robin@rchrist.io>]

From: Robin Christ <r.christ@partimus.com>

nodad option was added to nlcache NetlinkListenerWithCache addr_add, but not addr_add_dry_run,
breaking dry runs (--no-act) with the error

NetlinkListenerWithCache.addr_add_dry_run() got an unexpected keyword argument 'nodad'
