security/acme.sh: Use .conf suffix for /usr/local/etc/newsyslog.conf.d/
Rename files intended for installation to /usr/local/etc/newsyslog.conf.d/
to end with a '.conf' suffix.
Proposed changes to /etc/newsyslog.conf will only include files from the
/usr/local/etc/newsyslog.conf.d/ directory which end with '.conf' and do
not beginning with a '.' character. https://reviews.freebsd.org/D17086
