firmware: fix TOCTTOU race in sync/async RPC code.
...
Before this commit, the main loop in session code was laid like:
1. process_kern_queued_rpc
2. process_host_message
3. process_kern_message
If a host message (such as an RPC reply) caused the kernel to exit,
then any async RPCs would not complete, since RunFinished immediately
shuts down the kernel.
Fix this by reordering 1 and 2.

firmware: Use larger ARP cache
...
This works around a problematic interaction between ARP cache
expiry in smoltcp (with its 3 seconds timeout before a discovery
request is sent) and our TCP keepalive settings, where the timeout
is reached before the keepalive had a chance to be sent.
GitHub: Closes #1150 .
