Build System: Add option to disable IPV6 in orderly fashion

Browse Source 
If you define DISABLE_IPV6=yes to the config.inc, then the
rtems-bsd-config.h file will be modified accordingly and
the IPV6 kernel sources will not be built. This is easier
to manage and more correct than having a patch to do the same.
