quickshell-git: patch crash-relaunch env leak

After a crash relaunch, quickshell kept __QUICKSHELL_CRASH_* and the
instance-info fd in its environment, so every child it spawned inherited
them and any `qs` invocation from those children booted a duplicate
shell instead of running its command (phantom instances on every
menu-launched picker after a crash).

Patch carried on the fix-crash-env-leak branch of
https://github.com/omacom-io/quickshell
