broot 1.14.2: disable xorg-libxcb dependency

[rdslw]

As discussed with @herby: Please consider DISABLING "xorg-libxcb" dependency in broot port. This dependency is required only for clipboard which is still optional broot feature and I'm not sure if working well on macos at all. But the biggest problem is that it pulls in quite a bunch depencdencies only because of xorg-libxcb.

Prefered solution: remove one line from Portfile removing xorg-libxcb

broot: remove xorg-libxcb dependency

Fixes: #65661

[mf2k (Frank Schima)]

This doesn't fix the case where someone has xorg-libxcb installed already. The port will still use it and now have a hidden dependency on it. It's use must be disabled in the configure phase.

[herbygillot (Herby Gillot)]

Rust projects do not have a configure stage. They are built via cargo, and the closest thing would be features, which can change dependencies at build time.

broot's default set of features do not invoke clipboard features:

​https://github.com/Canop/broot/blob/e8a5f7687ac9efd30d549ce2dd1b83e452506215/Cargo.toml#L18

...which in turn should not pull in Xcb. We were not invoking the feature before, which could explain why @rdslw thought it wasn't working properly before.

Also, the broot packages built in the MacPorts buildbots should not be installing xorg libs, so the resultant packages shouldn't have any reference to libxcb.

I don't think there's any additional steps we can take here.

That said, we could probably reintroduce clipboard capabilities as a variant for this port, however.

I made sure that I had xorg-libxcb installed and did a source rebuild of broot. xorg-libxcb did not appear in the otool -L output.
