Bug#994395: cups: uses sides=one-sided by default

[Vincent Lefevre <vincent@vinc17.net>]

Additional information:

On both Debian 10 and Debian unstable, I get

$ ipptool -tv ipp://localhost/printers/print-1 get-printer-attributes.test | grep sides-
        sides-supported (1setOf keyword) = one-sided,two-sided-long-edge,two-sided-short-edge
        sides-default (keyword) = one-sided

I suspect that for some reason, the old client did not take
into account sides-default, but the fork does. I don't know
whether this is intended, but I couldn't find any information
about such a change.
