Looking to give up maintainership of print/cups-filters

[Naram Qashat]

Hello all,

I've been the maintainer of the print/cups-filter port for a while now, 
but I'd like to give it up to someone else. It does need an update 
currently (it is at 1.16.0 but needs to be updated to 1.19.0). I just 
don't have the means to deal with the potential problems that each 
update bring up. So, if anyone wants to take over maintainership of the 
port and update it, please submit a PR for it and I'll give the port up.

Thanks,
Naram Qashat
