ctdb-daemon: Drop attempt to connect to Unix domain socket
This was a weak attempt at exclusivity. PID file creation now does

s3/smbd: set FILE_ATTRIBUTE_DIRECTORY as necessary
Some VFS modules like GPFS will always return success from
SMB_VFS_GET_DOS_ATTRIBUTES() but only set a subset of the attributes. It
neither sets FILE_ATTRIBUTE_NORMAL nor FILE_ATTRIBUTE_DIRECTORY.
We already handle the case that the VFS stack returns with result==0 and
then add the FILE_ATTRIBUTE_NORMAL, regardless of the type of the
filesystem object. If we want to handle result==0 situation in the
SMB_VFS_GET_DOS_ATTRIBUTES() caller, then do it right by either setting
FILE_ATTRIBUTE_NORMAL or FILE_ATTRIBUTE_DIRECTORY.
