MDL-73645 theme_boost: Keep section breadcumb item in specific layouts

Browse Source 
Avoids removing the section breadcrumb nodes in the course module
context when the course uses the 'One section per page' layout.
Additionaly, it also removes the Courses and Category breadcrumb
nodes in the module contexts to be consistent with the way the
breadcrumbs are displayed in the course context.
