rrdtool @1.7.0: fix missing dependency for dejavu-fonts

[pdvnl]

rrdtool expects to find its default fonts DejaVuSans and DejaVuSansMono, but there is no dependency defined. Here I propose a patch to Portfile to add the missing depends-run dejavu-fonts.

Note: as rrdtool currently has nomaintainer you could assign it to me.

If you wish to maintain the port, feel free to modify the maintainers line appropriately in your patch.

[pdvnl]

add myself as maintainer.

Please submit this as a GitHub pull request if you can. Then it will be acted on far faster. Instructions are available in the MacPorts Guide if you need them.

Can openmaintainer be added?

[pdvnl]

I don't understand why. rrdtool had no maintainer, I worked myself through the code of rrdtool pango cairo and now think I know what I'm talking about, Ryan said to change it, so why?

[ctreleaven (Craig Treleaven)]

Re openmaintainer, see the Maintainers section under:

​https://guide.macports.org/#reference.keywords

Basically, adding openmaintainer gives prior approval to others to make minor corrections or updates to the port. It is the usual case, especially for port maintained by those without commit rights.

[pdvnl]

OK. now with open maintainer added.

next I'll try to make a PR.
