Actually include XrdSecEntity moninfo field in trace.

[bbockelm]

This logs the monitoring information associated with the Entity (as well as fixing an annoying text alignment issue in the extended attributes). With this, the xrootd authentication trace looks as follows for GSI:

I have taken a safer and more consistent approach by adding a gsi option that displays the subject DN when it is useful. See documentation at https://xrootd.slac.stanford.edu/doc/dev56/sec_config.htm#_Toc119617433

So, we will not be merging this. However, I will correct the nasty formatting error that you have pointed out.
