clipboard: update to fork updating x11-clipboard for xcb

[iceiix]

https://github.com/aweinstock314/rust-clipboard has no releases since 2019, there are a bunch of open pull requests: https://github.com/aweinstock314/rust-clipboard/pulls - this lack of a newer clipboard is holding back xcb (though there is a pull request to update it: aweinstock314/rust-clipboard#89 - could alternatively switch to a git version) so https://github.com/iceiix/stevenarella/security/dependabot is reporting several alerts:

Looking at the forks, https://github.com/ActuallyAllie/cli-clipboard is newer and has an updated xcb
Switch to use cli-clipboard to replace (rust-)clipboard
Update to use a fork of clipboard with an updated x11-clipboard in order to update xcb

[iceiix]

This may not completely fix the problem - allie-wake-up/cli-clipboard#13 (comment) is asking for a newer release of cli-clipboard for xcb > 1.0 (the git version has it, but last cargo release is 0.2.1 at the time of this writing (although https://github.com/ActuallyAllie/cli-clipboard/releases/ only goes up to 0.2.0)).

Breaks the wasm build:

maybe better to switch to an updated fork of clipboard than to cli-clipboard?

[iceiix]

Note: another alternative to cli-clipboard is arboard: https://crates.io/crates/arboard
It looks well-maintained. A patch to use it:

                     }
                 }

works on native, but has the same/similar problem as cli-clipboard (but not rust-clipboard) when compiling on wasm:

so not using arboard for now (but ultimately, would like to use a properly supported clipboard project going forward instead of having to pin a git version, in order to more easily support updates, including from dependabot alerts).
