    elf: Keep using minimal malloc after early DTV resize (bug 32412)

    If an auditor loads many TLS-using modules during startup, it is
    possible to trigger DTV resizing.  Previously, the DTV was marked
    as allocated by the main malloc afterwards, even if the minimal
    malloc was still in use.  With this change, _dl_resize_dtv marks
    the resized DTV as allocated with the minimal malloc.

    The new test reuses TLS-using modules from other auditing tests.
