net-misc/asterisk: security bump (init script).

The details is outlined in:

Bug:  https://bugs.gentoo.org/602722

This only affects things if you can trick the sysadmin to run
/etc/init.d/asterisk checkperms.

Took the opportunity to tighten permissions on /var/lib/asterisk and
/var/spool/asterisk as well, and double checked that on new install
these are in fact correct.  Permissions on /var/spool/asterisk/recording
was missed previously and left root:root as per the standard asterisk
install Makefile.
