print/gutenprint: update to 5.2.12
https://sourceforge.net/projects/gimp-print/files/gutenprint-5.2/5.2.12/
The -ijs and -foomatic backends have been removed by upstream,
leaving -cups as the sole choice of backend. Therefore, the -base
and -cups ports have been merged into the main gutenprint port
and the obsolete components have been removed.
