support wayland copy to clipboard

[extrawurst]

according to @1wilkens in #390 our current copy to clipboard binaries may not cover wayland (correct me if I am wrong).

maybe we can use this opportunity to cleanup the support for multiple fallback programs for running copy to clipboard:

• use which on all platforms
• have a list of platforms specific programs
• try them all before erroring out

[1wilkens]

While we can certainly do that, we could also use a rust library to handle the clipboard. There are several choices, but copypasta seems to be the most up-to-date one. I can understand if you don't want to add a (potentially) heavy dependency, however we already included which just for clipboard support, so I would actually use the abstraction from a proper clipboard library.

@1wilkens good thinking, but we have been there and tried that and reverted it because of dynamic dependencies that these libraries introduce: #261

which only needs libc and can still compile to a static binary

[1wilkens]

My bad, I should have looked maybe ;) In this case, the proposed solution seems good. I'll try to address the wayland part in a PR soon :)

Can this be reopened? Using wl-copy on Wayland here. Great tool gitui!
