Subject: [PATCH] lib/cinder:configure tgt even if the package was purged

On Ubuntu, after a successful ./stack.sh and ./unstack.sh, if one
"apt-get purge tgt", then the directory /etc/tgt/stack.d/ still
exist (i.e it is not purged) but /etc/tgt/targets.conf is removed.
Thus any subsequent ./stack.sh would fail to configure
/etc/tgt/targets.conf properly.
