xentools20 updated to 2.0.6

[Juan RP <juan%xtrarom.org@localhost>]

Hi, I've just updated sysutils/xentools20 package to 2.0.6, unpack it
on pkgsrc/sysutils and remove the old xentools20 directory.

http://www.xtrarom.org/pkgsrc/xentools20.tar.gz

Works fine for me, please report any problem with this.

TODO:
        
        * Install scripts into ${EGDIR}
        * Use PKG_SYSCONFDIR for configuration files
        
Thanks.
