Do not proxy some endpoints to the generic Synapse worker

These endpoints should not be proxied to a generic Synapse worker
without other preparation (setting up stream writers, sending traffic
to a specific stream writer, etc.).

Disabling them for now. In the future, we'd like to fix up our awk
script to disable them automatically.

This is a fix up for 058fedff91
