Bug 7885 - Change filename of TransferLog suggested by packages to fit with logrotate

The apache accesslogs suggested by the default config files are called
*_log, which results in them not getting picked up by logrotate, which
looks for *.log. This patch changes the suggested filenames to *.log.

To test:
Not much to test here, just apply the patch and check that all
occurences of TransferLog and CustomLog are now on the form *.log

All the lines where these occur are commented out, so this will
not actually change any behaviour.
