[PM-17784/PM-17588] Flatpak & Mac Store SSH Agent

[quexten]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-17784
https://bitwarden.atlassian.net/browse/PM-17588

📔 Objective

Both mac app store and flatpak sandbox the process list, so the information we get back when inspecting the process for the pid obtained by peercred fails. This should not crash, or stop the ssh agent, but instead return "unknown process".

Further, flatpak does not have access to the home directory and requires a separate path configured that other apps can access without changing any permissions.
