[PATCH] main/process: Add extra sockname debugging

[Richard Purdie <richard.purdie@linuxfoundation.org>]

We're struggling to understand how bitbake.sock can sometimes disappear
in live builds when we can't see where it could have been deleted.
This causes connection failures to the server and failed builds.

Add some extra debugging around the server log and client retry
log messages to give more information for the next time this issue
occurs.
