libio: Set _vtable_offset before calling _IO_link_in [BZ #32148]
Since _IO_vtable_offset is used to detect the old binaries, set it in _IO_old_file_init_internal before calling _IO_link_in which checks _IO_vtable_offset. Add a glibc 2.0 test with copy relocation on _IO_stderr_@GLIBC_2.0 to verify that fopen won't cause memory corruption. This fixes BZ #32148. Signed-off-by: H.J.
