logsys: Make logging of totem work again

Because of change in libqb (9abb686) logging of TOTEM subsystem stopped
working.

Instead of rely on previous behavior (implicit substring match), all
totem files are now explicitly given.

Also QB subsystem now uses comma separated filelist instead of previous
function calling.
