There's a merged pull request on the void-packages repository

common/xbps-src/shutils/chroot.sh: support importing other keys
https://github.com/void-linux/void-packages/pull/47291

Description:
When packages in `hostdir/binpkgs` are signed, it causes `xbps-src` to annoyingly request to import the associated key (every time, in the case of automation tools like `xxbuild` or `ymir`). This allows the user to add their personal public key `.plist` to `etc/repo-keys/` so this prompting does not happen.

#### Testing the changes
