MFC r352304, r352540

r352304:
No longer mlock() ntpd pages by default in memory thus allowing its
pages to page as necessary.

To restore historic BSD behaviour add the following to ntp.conf:
	rlimit memlock 32

Discussed on:	freebsd-current@ between Sept 6-9, 2019

r352540:
Follow up on r352304 which disabled default mlockall() at startup.
Unfortunately though the original tarball supports this in ./configure
(for Linux), to fully support disabling of mlockall() by default requires
a little extra help otherwise the following is logged in syslog:

	Cannot set RLIMIT_MEMLOCK: Operation not permitted
