  Fix for issues #3581, #1481 and #7650:

  1. The assumptions in check_node() were too restrictive:

       - Hardware addresses with universal_local_bit=1 are valid
         (locally administered).

       - Many of the tested functions (including uuid.getnode())
         may return valid RFC 4122 random node IDs. These are pretty
         much random 48-bit values with the multicast bit set to 1.

  2. _unixdll_getnode() calls _uuid_generate_time(), which may be None
     on some platforms. The resulting TypeError is now caught.
