    aarch64: Fix missing BTI protection from dependencies [BZ #26926]

    The _dl_open_check and _rtld_main_check hooks are not called on the
    dependencies of a loaded module, so BTI protection was missed on
    every module other than the main executable and directly dlopened
    libraries.

    The fix just iterates over dependencies to enable BTI.

    Fixes bug 26926.
