Your first version was trying to fetch 
https://codeload.github.com/sergiomb2/ufraw/tar.gz/g20161113?dummy=/sergiomb2-ufraw-g20161113_GH0.tar.gz
But you should fetch this (note the tag 6d3259a after tar.gz/)
https://codeload.github.com/sergiomb2/ufraw/tar.gz/6d3259a?dummy=/sergiomb2-ufraw-6d3259a_GH0.tar.gz

So you need to tune your Makefile to create link like above.

According to this 
https://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/makefile-distfiles.html#makefile-master_sites-popular
you need to set GH_ACCOUNT,  GH_PROJECT and GH_TAGNAME=6d3259a to create 
right URL:

${GH_ACCOUNT}/${GH_PROJECT}/tar.gz/${GH_TAGNAME}?dummy=/

This works for me

PORTNAME=       ufraw-devel
PORTVERSION=    g20161113
CATEGORIES=     graphics
MASTER_SITES=   GH
#DISTNAME= 
${GH_ACCOUNT}-${GH_PROJECT}-${GH_TAGNAME}${DISTVERSIONSUFFIX}

MAINTAINER=     freebsd@dreamchaser.org
COMMENT=        Read and manipulate raw images from digital cameras

LICENSE=        GPLv2

USE_GITHUB=     yes
GH_ACCOUNT=     sergiomb2
GH_PROJECT=     ufraw
GH_TAGNAME=     6d3259a

.include <bsd.port.mk>


You should create distinfo file with checksum first:
