graphics/ufraw fails to compile on 11-stable

[Walter Schwarzenfeld]

Seems was a paste problem, line 41 started under the "n" of sprint

sprintf (th->date, "%04d:%02d:%02d %02d:%02d:%02d",
t->tm_year+1900,t->tm_mon+1,t->tm_mday,t->tm_hour,t->tm_min,t->tm_sec);

Btw, this is a bug, so I would suggest make a PR.
