cups-genppd is installed as "cups-genppd.5.2".
The docs reference "cups-genppd".
It needs a symlink.

gutenprint: fixes around genppd
* in papers.xml, rename "Greeting Card" paper format names to not contain
decimal points ("."), as gutenprint's internal list handling rejects
points in element names. I guess these paper formats never really
worked, but I can't really test this for lack of a supported printer.
* create symlink cups-genppd to cups.genppd.5.2 to match documentation.
