chore: update psiphon (#1522)

It seems there's an issue by which some `replace` directives in the
`go.mod` used by Psiphon aren't picked up by us. The thing is that
`replace` only works for the main module. We thus asked for
clarification but we can merge this PR anyway, since it helps us to find
dependency intersection between snowflake and psiphon (I am thinking
mainly in terms of refraction-networking/utls).

See ooni/probe#2690
