[WIP] fd: add completions
https://github.com/void-linux/void-packages/pull/19489

Description:
`fd` generates completion files for most shells during compilation, but the installation step doesn't add them to destdir.

~I may need some help with this, as the current template does install them (they show up in `masterdir/destdir/fd-7.4.0/` at the correct locations after `xbps-src install fd`), but they are still missing from the package after `xbps-src pkg`. I don't understand why.~ It was a caching issue...

As for using `vcopy` instead of `vinstall`, the path where the completion files are generated contains a hash. Maybe someone versed in rust's build system knows a better way than using a glob pattern.

I also noticed, that there is now a `/usr/.crates2.json` in the package, looking into it.
