The412Banner 566018674f Steam updates: the client is not uid 0 in the session - drop that test ...

The session's proot runs with -i <app uid>, and the rootfs names that uid
root, so the client calls itself root while geteuid() returns the app's
uid. The read-only retry required geteuid() == 0 and never ran: the
Proton Experimental (ARM64) update still failed with Missing file
permissions on wineopenxr.dll (2026-09-26 16:07, 2,471 read-only files).

Also recognise the client by the path it was started by: the kernel's
/proc/self/exe names proot's loader for every process in the session.
