ETCKEEPER_AVOID_PACKAGELIST and AVOID_PACKAGELIST=1 defined in etckeeper.conf

Because it is slow that some package manager make the packagelist(eg, rpm
 -qa), high-level package manager might time out.
If you think that the packagelist is unnecessary, set AVOID_PACKAGELIST=1.
Or if you want to avoid it temporarily,
you can use environment variable ETCKEEPER_AVOID_PACKAGELIST=1 .
(eg, ETCKEEPER_AVOID_PACKAGELIST=1 zypper update).
