Update linux binary expectations (#12622)

Fixes #12585

This changes the expectations for installed binaries on linux based on
work
that @jirutka has done for Alpine.

In particular, we now put the cli in place as `bin/zed` and the zed
binary as
`libexec/zed-editor`, and assume that packagers do the same.
