Berry: add patch to address zombie process issue
https://github.com/void-linux/void-packages/pull/46416

Description:
#### Testing the changes
- I tested the changes in this PR: **briefly**

I tested berrywm on a VM and it ran, however I'm stuck at a blank screen without any errors or warnings from Xorg - I'm not sure if this is normal behaviour with something I haven't configured.

#### Local build testing
- I built this PR locally for my native architecture, (x86_64-glibc)

There's no new version of berry, but they provide a patch which I've imported that seems to fix the issue as mentioned in https://github.com/void-linux/void-packages/issues/46039
