Recent versions of docker in combination with the upstream systemd unit files pass an incredibly high `ulimit -n` to the docker container, up to 1 billion. That causes minute high delays and CPU spinning when connecting to VNC while it enumerates all the file descriptors. See #2045

Description
See #2045. Basically what #2045 (comment) proposed. If the ulimit is high, defensively lower it.
Motivation and Context
Recent versions of docker in combination with the upstream systemd unit files pass an incredibly high
ulimit -nto the docker container, up to 1 billion. That causes minute high delays and CPU spinning when connecting to VNC while it enumerates all the file descriptors.Types of changes
