remove unneeded LOG_DEBUG when not compiling with DEBUG support

when ngircd is build without DEBUG enabled, LOG_DEBUG messages
are always discarded.

To avoid the extra code, ngircd has a LogDebug() wrapper which
gets removed by the compiler when compiling without DEBUG defined.

Update a few functings which were using the
Log(LOG_DEBUG, .. interface directly without #ifdef DEBUG guards.
