tools: Remove Hybrid 6 conversion tools.

Browse source 
Hybrid 6 is old enough that the conversion tools can go away now.
They are for I and K lines; the ircd.conf converter was already removed.

This removes compiler/analyzer warnings about these tools.

Note: If you use different names in ircd.conf, you must 'touch' the
specific names.
6.
If you are upgrading from Hybrid 5 or Hybrid 6, the config file has
changed drastically...
There is a utility to convert your old config file to the new format.
In prefix/bin there is something called "convertconf". Its usage is:
./convertconf (old config file to convert) (converted file name)
Convertconf will NOT convert I: lines. You must use "convertilines"
for this which contains a much superior method of conversion and
will group I: together under one auth {};.
Once this is done, move your new config to prefix/etc/ircd.conf and
EDIT IT! There are still things that need changing in the config,
including the fact that classes MUST be above auth/connect blocks!
7.
If you are upgrading from Hybrid 5 or Hybrid 6, the kline file has
also changed...
There is a utility to convert the old kline configuration file to the
new format. In prefix/bin there is a program called "convertklines".
Its usage is: ./convertklines (old kline.conf filename) (new
kline.conf filename) (dline.conf filename).
Once this is done, move the new files into the prefix/etc/ directory
under their proper names. By default, the kline file is named
kline.conf and the dline file is named dline.conf.
