TT#37257 Stop creating /tmp/ngcp-installer-cmdline.log as it gone after reboot

The file /tmp/ngcp-installer-cmdline.log is available when GRML is running only
and will gone right after the reboot. In the same time original
"${TARGET}/etc/ngcp-installer/config_deploy.inc" is also available
during GRML is running and will stay after the reboot.

For all the time I had no reason to check /tmp/ngcp-installer-cmdline.log,
as I always used config_deploy.inc directly (which is also covered by etckeeper).

Removing it as a part of minimizing log files program.
