Switch from crate clipboard to arboard

This avoids a dependency via x11-clipboard to an old version of xcb,
v0.3. Problems and annoyances with xcb v0.3 include

- safety: aweinstock314/rust-clipboard#90
- build script depends on python
- won't build in a sandbox, as it writes to the source directory
