LU-8285 test: Allow LNet logging as default in autotest

The default in the local.sh configuration file for autotest
is to turn off all logging from three subsystems: lnet, lnd,
and pinger.  There is no good reason to be doing this and
this could be hiding important logs highlighting bugs.

This patch makes the default to allow all subsystems to log.
