libcaca 0.99b19

The old formula referred to
http://caca.zoy.org/files/libcaca/libcaca-0.99.beta18.tar.gz which
cannot be downloaded at the moment. A 0.99 beta 19 was found at
fossies.org and it seems to work. Using beta 19 also obviates the need
for the patch in the current formula.
libcaca: add 0.99b19 bottle.

Closes #29859.
