build: explicitly whitelist symbols in NetworkManager binaryth/nm-symbols

- this allows the linker to drop unused symbols via link-time optimization
  or with --gc-sections:

    git clean -fdx
    ./autogen.sh --enable-ld-gc --enable-ifcfg-rh --enable-ifupdown \
        --enable-ifnet --enable-ibft --enable-teamdctl --enable-wifi \
        --with-modem-manager-1 --with-ofono --with-more-asserts \
        --with-more-logging
    make -j20
    strip ./src/NetworkManager

  gives 2822840 vs. 2625960 bytes (-7%).

- this also gives more control over the symbols that are used by the
  plugins. Yes, it means if you modify a plugin to use a new symbols,
  you have to extend NetworkManager.ver file.
  You can try to run the script for that, but be sure to enable
  debugging option and all plugins.

    ./tools/create-exports-NetworkManager.sh update
