cherrytree: update to 0.99.51
https://github.com/void-linux/void-packages/pull/40444

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

---

To explain the changes, cherrytree now has tests that run as part of the build process right after building the program. These tests require access to an X server, and I don't think it would be good to run the entire build under `xvfb-run` or something like that. Cherrytree also uses a bundled version of gtest and will attempt to build it regardless of whether tests are enabled unless a configure arg is set and gtest is available in the environment.
