    configure.ac: Remove --disable-znodelete options
    
    There is no reason to disable this linker flags, and we are not going to
    add this option in our meson build system, so remove it from autotools
    too to be on par. If anyone complains with a valid use-case we can add
    them back.
    
    Keeping -Bsymbolc for now because it is used for refdbg and Debian has a
    package that build glib with that flag.
