staging/lustre/mdt: set ATTR_xTIME_SET to make atime update properly

To make atime update properly between 1.8 client and 2.x server,
this patch includes the following fixes:
- if MDS_ATTR_xTIME is set without MDS_ATTR_xTIME_SET and the client
  does not have OBD_CONNECT_FULL20, convert it to LA_xTIME in
  mdt_setattr_unpack().
- set both MDS_ATTR_xTIME | MDS_ATTR_xTIME_SET for timestamps in
  ll_prepare_close(). This allows us to fix the server-side timestamp
  setting in the future.
- remove attr_unpack() and convert the flags from MDS_ATTR_ to LA_*
  directly in mdt_attr_valid_xlate() instead.
- improve sanityn.sh test_23().
