Stop relying on binary location to be in libexec on Linux (#13374)

Browse source 
This fixes #13360 by adding fallback directories that are searched by
the CLI if the main executable cannot be found in the `libexec`
directory.

Release Notes:

- Added the fallback directories `lib/zed` and `lib/zed-editor` for the
main executable search in the CLI
([#13360](https://github.com/zed-industries/zed/issues/13360)).

@ -89,7 +89,7 @@ Thank you for taking on the task of packaging Zed!
Zed has two main binaries:
* You will need to build `crates/cli` and make it's binary available in `$PATH` with the name `zed`.
* You will need to build `crates/zed` and put it at `$PATH/to/cli/../../libexec/zed-editor`. For example, if you are going to put the cli at `~/.local/bin/zed` put zed at `~/.local/libexec/zed-editor`.
* You will need to build `crates/zed` and put it at `$PATH/to/cli/../../libexec/zed-editor`. For example, if you are going to put the cli at `~/.local/bin/zed` put zed at `~/.local/libexec/zed-editor`. As some linux distributions (notably Arch) discourage the use of `libexec`, you can also put this binary at `$PATH/to/cli/../../lib/zed/zed-editor` (e.g. `~/.local/lib/zed/zed-editor`) instead.
* If you are going to provide a `.desktop` file you can find a template in `crates/zed/resources/zed.desktop.in`, and use `envsubst` to populate it with the values required. This file should also be renamed to `$APP_ID.desktop`, so that the file [follows the FreeDesktop standards](https://github.com/zed-industries/zed/issues/12707#issuecomment-2168742761).
* You will need to ensure that the necessary libraries are installed. You can get the current list by [inspecting the built binary](https://github.com/zed-industries/zed/blob/059a4141b756cf4afac4c977afc488539aec6470/script/bundle-linux#L65-L70) on your system.
* For an example of a complete build script, see [script/bundle-linux](https://github.com/zed-industries/zed/blob/main/script/bundle-linux).
