foomatic fix

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

After upgrading foomatic-filters I have been hit by this error:
Can't use 'defined(@array)' (Maybe you should just omit the defined()?) 
at /usr/pkg/bin/foomatic-rip line 1477.

After looking for similar errors in other software, I tried
this with success:

Should I commit this as a patch to the package?
