coredevice: Handle prematurely closed sockets in comm_kernel receive loop
...
recv() returns 0 instead of data if the socket has already
been closed. This is translated into a zero-length list on
the Python layer. Previously, the code would enter an
infinite loop if the socket was closed while attempting
to receive data.

coredevice: Re-enable TCP keepalive
...
This partially reverts commit b5e1bd3fa2
,
which had removed keepalive. This, however, led to experiments
hanging forever if the core device had dropped the connection
(e.g. to a kernel CPU panic, or the device being rebooted).
The chosen keepalive settings are fairly conservative (with the
10 s timeout) to avoid any possible interaction with smoltcp's
3 s ARP try interval (see GitHub issue #1150 ), even though this
should be a non-issue now due to the larger ARP cache.
