bind: Update bind.keys

A multi-year DNSSEC root key update is in progress, as described at
https://www.isc.org/downloads/bind/bind-keys/. This change refreshes the
bind.keys file, ensuring that the new key, in place as of 2018-10-11,
will be recognized and trusted.

+# The bind.keys file is used to override the built-in DNSSEC trust anchors
+# which are included as part of BIND 9.  As of the current release, the only
+# trust anchors it contains are those for the DNS root zone ("."), and for
+# the ISC DNSSEC Lookaside Validation zone ("dlv.isc.org").  Trust anchors
+# for any other zones MUST be configured elsewhere; if they are configured
+# here, they will not be recognized or used by named.
+#
+# The built-in trust anchors are provided for convenience of configuration.
+# They are not activated within named.conf unless specifically switched on.
+# To use the built-in root key, set "dnssec-validation auto;" in
+# named.conf options.  To use the built-in DLV key, set
+# "dnssec-lookaside auto;".  Without these options being set,
+# the keys in this file are ignored.
+#
+# This file is NOT expected to be user-configured.
+#
+# These keys are current as of Feburary 2017.  If any key fails to
+# initialize correctly, it may have expired.  In that event you should
+# replace this file with a current version.  The latest version of
+# bind.keys can always be obtained from ISC at https://www.isc.org/bind-keys.
