advice: remove use of global advice_add_embedded_repo

Browse Source 
The external use of this variable was added in 532139940c (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.
