websocket: Fix printf of 32-bit number treated as 64-bit
websocket: Fix printf of 32-bit number treated as 64-bit

On ARM sizes can be 32-bit and we were using a 64-bit format.
This probably would have crashed if it had ever been reached.

Fixes this warning:

src/websocket/websocketconnection.c:629:3: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 5 has type 'gsize' [-Wformat=]
   g_message ("%s is trying to frame of size %" G_GUINT64_FORMAT " or greater, but max supported size is 128KiB",

Closes #1636
