    [gdb/testsuite] Fix inter-cu refs in inlined_subroutine-inheritance.exp
    
    When running gdb.dwarf2/inlined_subroutine-inheritance.exp with board
    cc-with-dwz, we run into:
    ...
    dwz: inlined_subroutine-inheritance: Couldn't find DIE referenced by \
      DW_AT_abstract_origin
    ...
    
    The problem is that the DW_AT_abstract_origin attributes refer to DIEs in
    other CUs, while the references are encoded using the cu-relative encoding
    DW_FORM_ref4.
    
    Fix this by forcing the references to use DW_FORM_ref_addr.
    
    Tested on x86_64-linux.
    
    Tested with commit c24bdb023c "Introduce dwarf2_cu::get_builder" reverted,
    and verified that the test-case fails in the same way before and after this
    patch.
