chg: server exited with code 0 without being connectable is an error
Before this patch, if the server started by chg has exited with code 0 without
creating a connectable unix domain socket at the specified address, chg will
exit with code 0, which is not the correct behavior. It can happen, for
example, CHGHG is set to /bin/true.
This patch addresses the issue by checking the exit code of the server and
printing a new error message if the server exited normally but cannot be
reached.
