Remove some unused buildsym functions

Now that the DWARF reader uses the builder-based API, we can remove a
few "legacy" functions that were only ever called by it.

    The compunit symtab pointer ("cust") is returned from both start_symtab
    and end_symtab to simplify the debug info readers.
 
-   There are minor variations on this, e.g., dwarf2read.c splits end_symtab
-   into two calls: end_symtab_get_static_block, end_symtab_from_static_block,
-   but all debug info readers follow this basic flow.
-
-   Reading DWARF Type Units is another variation:
-
-   scoped_free_pendings free_pending;
-   cust = start_symtab (...);
-   ... read debug info ...
-   cust = end_expandable_symtab (...);
-
-   And then reading subsequent Type Units within the containing "Comp Unit"
-   will use a second flow:
-
-   scoped_free_pendings free_pending;
-   cust = restart_symtab (...);
-   ... read debug info ...
-   cust = augment_type_symtab (...);
