That's correct: umask is set for a shell session through an init file
(.bash_profile, /etc/profile or similar) and it persists only for that
session. I don't know if there is a tramp way of doing it, but you
can certainly do what you want by adding

umask 022

to the shell initialization file of the user on the remote host.
