extensions/extb_ssl.c: make certfp parameter case-insensitive
I had the idea that maybe these should be case-sensitive because some
encodings (like Base-64) are. But it turns out it's better to
prioritise not breaking existing configurations / channel mode lists,
and just revisit this in future maybe.
