[WIP] arduino: update to 1.8.11.
Patches failed so I deleted them. Cannot test if the patches are needed until I can get arduino to compile.

Unfortunately, the template fails to compile because of issue #11718

A patch file from https://github.com/void-linux/void-packages/pull/18673.patch is attached
