plasma-vault will require gocryptfs in Plasma 6.4

[Nate Graham]

Hello packagers!

This is a heads-up that in Plasma 6.4.0, plasma-vault will require 
gocryptfs. I've added it as a runtime dependency in 
https://invent.kde.org/plasma/plasma-vault/-/commit/49463366e488642c7a2368f964605595de94cca5, 
so make sure that you either note this, or that whatever system you use 
for detecting runtime dependencies is working!
