Subject: advice: remove use of global advice_add_embedded_repo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The external use of this variable was added in 532139940c9 (add: warn
when adding an embedded repository, 2017-06-14). For the use-case it's
more straightforward to track whether we've shown advice in
check_embedded_repo() than setting the global variable.
