wesnoth: update to 1.18.0.

[iFoundSilentHouse]

• I tested the changes in this PR: YES
  Checked out new compaign.

• I built this PR locally for my native architecture, (x86_64-glibc)

Patch for boost is no longer needed as it was commited to 1.17 version.
Added libcurl as changelog says wesnoth now needs it for compiling.

For x86_64 build is fine locally (I've checked it multiple times). Though for musl some extra patching needs to be done. Working on it.

[iFoundSilentHouse]

I built template successfully on: x86_64, i686, x86_64-musl, aarch64-musl. Will add proofs if CI checks will fail

Added pull request on wesnoth to fix musl build bug: wesnoth/wesnoth#8628
Patch from https://patch-diff.githubusercontent.com/raw/wesnoth/wesnoth/pull/8628.patch doesn't work, though patch made locally works fine.

6/7 Test #6: SDL2_WEBP_SUPPORT ................***Failed    0.00 sec

I don't know what to do. Old SDL2_image version doesn't seem to be a thing

Changes:

• SDL2_image: for webp support added patch to SDL2_image as there's no command that worked for build using dynamic linking.
• wesnoth: 1) Added patch that allows musl to build; this code doesn't change functionality 2) Disabled audio test - obviously, virtual environment doesn't have sound card.
  Everything works. @classabbyamp

• SDL2_image: for webp support added patch to SDL2_image as there's no command that worked for build using dynamic linking.

Instead of adding a patch, add configure_args="-DSDL2IMAGE_WEBP=ON" to SDL2_image's template.

If done correctly, this should be part of the configure step's output for SDL2_image:

-- SDL2_image: Using system libwebp
-- Found webp: /usr/lib/libwebp.so  
-- Dynamic libwebpdemux: libwebpdemux.so.2
-- Dynamic libwebp: libwebp.so.7

I tried it. Didn't work. Maybe I was too tired bruteforcing the answer and did something wrong. I'll try it againg

You might need to ./xbps-src clean SDL2_image first for some reason.

Thanks for working on the update, by the way. I do want to play Wesnoth 1.18 at some point.

Thanks a lot for your reviews! :)

Added wesnoth developers' patch to fix musl instead of mine: wesnoth/wesnoth#8649
