commandserver: handle backlog before exiting

Previously, when a chg server is exiting, it does not handle connected
clients so clients may get ECONNRESET and crash:

  1. client connect() # success
  2. server shouldexit = True and exit
  3. client recv() # ECONNRESET

d7875bfbfccb makes this race condition easier to reproduce if a lot of short
chg commands are started in parallel.

This patch fixes the above issue by unlinking the socket path to stop
queuing new connections and processing all pending connections before exit.

#require bzr bzr114

  $ . "$TESTDIR/bzr-definitions"

The file/directory replacement can only be reproduced on
bzr >= 1.4. Merge it back in test-convert-bzr-directories once
this version becomes mainstream.
