mupen64plus: update to 2.6.0
#### Testing the changes
- I tested the changes in this PR: **briefly**

#### New package
- This new package conforms to the [package requirements](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#package-requirements): **YES**

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

#### Notes
- As the Boost libraries are no longer required, they have been removed from the dependencies.
- Two of the patches have been removed because the new version incorporates the respective changes.

#### Pending checks
- For some reason, the launcher (mupen64plus-ui-console) still displays 2.5.9 as the version number, although the core library (mupen64plus-core) displays 2.6.0, as expected.
- The "ui-console-pic" patch might need to be updated.
- It looks like the ARM architecture is now supported, as seen in https://github.com/mupen64plus/mupen64plus-video-glide64mk2/blob/eb6484ee309f2aa4dfeff44c4fdd3755c97f812d/projects/unix/Makefile#L111.
