nodejs: security bump to version 6.11.1

Fixes CVE-2017-1000381 - The c-ares function ares_parse_naptr_reply(), which
is used for parsing NAPTR responses, could be triggered to read memory
outside of the given input buffer if the passed in DNS response packet was
crafted in a particular way.  This patch checks that there is enough data
for the required elements of an NAPTR record (2 int16, 3 bytes for string
lengths) before processing a record.
