Updated to only mark ECB as not requiring an IV.

The previous patch has been updated to make random IV for all modes except ECB.
Since I did not see any other comments about the patch, perhaps this can be
commited to CVS? Sorry for being pushy, I am juggling a bunch of these patches
while I continue to test GNU-crypto with various applications and it is
starting to become a pain...
