print_tag_downloads(): Free ref variable
Make sure the ref variable is freed if we build a
"$basename-$version"-style ref.
This fixes following memory leak seen with "PATH_INFO=/cgit/refs/":
==8784== 323 bytes in 29 blocks are definitely lost in loss record 41 of 53
==8784== at 0x4C2C04B: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==8784== by 0x56F2DF1: strdup (in /usr/lib/libc-2.17.so)
