irc/minbif latest as of date of PR submission

>Description:
irc/minbif requires imlib2, regardless of whether it's actually
needed for the port to function. In reality, imlib2 is only
needed when the user selects caca support. I've attached a patch
that fixes the dependencies and disables libcaca and imlib2
support if the user doesn't select caca.
>How-To-Repeat:
Try to build minbif without imlib2 installed.
Observe minbif installation recurse into imlib2 port, despite not
needing it.
>Fix:
See below.
