Disable fluidlite in CI.

[BillyONeal]

Fluidlite, added 3 days ago in #13006 , tries to install the same files as fluidsynth; it's similar to the 'boringssl' situation. Given that fluidlite doens't have any dependencies, this change disables that one rather than fluidsynth,

Should we add warning or error messages in portfile.cmake to warn users about conflicts?

Should we add warning or error messages in portfile.cmake to warn users about conflicts?

In this case I think we're OK without it because these 2 libraries appear somewhat specialized and it's unlikely that a user is going to want them both at once. We do have a warning like that for boringssl but that's because so many libraries list openssl as an explicit dependency, but nothing declares fluidsynth as an explicit dependency.

On the other hand I can see an argument that we should be consistent about it....

Added warning message

[Ghabry]

Oh. Yeah, sorry. I didn't consider this conflict. Disable it.

There is no use case for both libs at once (you only pick lite when you don't want this huge glib dependency)
