* Control token: a closing window removes only its own token and discovery files (#8794)
Under Flatpak each instance has its own loopback, so a second window
binds the same port number as the first and writes the same
<port>.token, <port>.pid and current.port in the shared data folder.
At exit the first window deleted them all, unconditionally, leaving the
second window running with no token file a client could read.
remove_token_file now takes this launch's token and removes the token
and process files only while the file still holds it; the process id
can't tell instances apart, as every Flatpak instance has the same one.
remove_current_port also takes the token and keeps the discovery file
while another launch's token file holds that port, and removes
current.pid with current.port (it was left behind).
