Fixes TIFFImagePlugin ICC color profile saving.
...
In the TIFF code saving icc_profile is conditional on tag_v2 being set which doesn't make sense to me. I believe this is merely an indentation typo.
I've been trying to save TIFFs with im.info['icc_profile'] set and compression=raw, but unfortunately this results in TIFFs without ICC color profiles.
With the attached patch TIFFs with said conditions will be saved with the profile set in im.info['icc_profile'].
Note: There are a number of different conditions that need to be met for code to succeed in saving with the profile since it branches between using libtiff and ImageFile._save(..), and the libtiff code does not currently save the ICC color profile.
For instance setting compression=tiff_lzw will result in using libtiff and no profile will be saved.

Haven't excercized all of the metadata that we're allowing yet,
