Mk/bsd.options.desc.mk: sort out TOMCAT options

[vvd]

Summary

1. Removed EOLed tomcat 6, 7 and 8.
2. Replaced tomcat10 with tomcat101.
3. Changed TOMCAT*_DESC to more correct.

There are less than 5 ports in tree making use of this as far as I can tell so is there a need for TOMCAT to be in bsd.options.desc.mk at all?
This should also be split into separate commits.

I was surprised myself when I discovered TOMCAT*_DESC in Mk/bsd.options.desc.mk.
I found 3 ports only: devel/opengrok, www/axis2 and accidentally missed www/madsonic.

This should also be split into separate commits.

Disagree: 1) separately, the meaning of the changes will not be clear; 2) the patch is already very small.

I think this is fine.
