app-backup/snapper: version bump 0.8.4, add bash-completion support

In this version, we also add bash-completion support
But it's rather better to push bash-completion support to upstream,
instead of maintaining it downstream.

thanks 'Xu Weiping' for the contribution

Closes: https://bugs.gentoo.org/697480
