net/bind916: update to 9.16.30

	--- 9.16.30 released ---

5899.	[func]		Don't try to process DNSSEC-related and ZONEMD records
			in catz. [GL #3380]

5890.	[bug]		When the fetches-per-server quota was adjusted
			because of an authoritative server timing out more
			or less frequently, it was incorrectly set to 1
			rather than the intended value.  This has been
			fixed. [GL #3327]

5888.	[bug]		Only write key files if the dnssec-policy keymgr has
			changed the metadata. [GL #3302]

5823.	[func]		Replace hazard pointers based lock-free list with
			locked-list based queue that's simpler and has no or
			little performance impact. [GL #3180]
