Fix the build on 9.x.
Add a missing include so that the port builds on 9.3-{amd64,i386}:
/wrkdirs/usr/ports/graphics/hugin/work/hugin-2015.0.0/src/hugin_cpfind/localfeatures/RansacFiltering.cpp: In function 'int genint(int)':
/wrkdirs/usr/ports/graphics/hugin/work/hugin-2015.0.0/src/hugin_cpfind/localfeatures/RansacFiltering.cpp:28:31: error: 'rand' was not declared in this scope
return (int)((double)rand()*x/(double)RAND_MAX);
^
/wrkdirs/usr/ports/graphics/hugin/work/hugin-2015.0.0/src/hugin_cpfind/localfeatures/RansacFiltering.cpp:28:43: error: 'RAND_MAX' was not declared in this scope
return (int)((double)rand()*x/(double)RAND_MAX);
^The quarterly branch is not affected, it still contains hugin 2013.0.0.
