Remove netatm from HEAD as it is not MPSAFE and relies on the now removed

NET_NEEDS_GIANT.  netatm has been disconnected from the build for ten
months in HEAD/RELENG_7.  Specifics:

- netatm include files
- netatm command line management tools
- libatm
- ATM parts in rescue and sysinstall
- sample configuration files and documents
- kernel support as a module or in NOTES
- netgraph wrapper nodes for netatm
- ctags data for netatm.
- netatm-specific device drivers.
