In the OPAL_ENABLE_FT_CR code path there used to be a variable
'mca_base_component_distill_checkpoint_ready' which got removed.
The FT code was not compiling and while trying to get it to compile
again the old variable was #ifdef'd out. This re-introduces the
variable with a new name 'opal_base_distill_checkpoint_ready'
and enables the code previously #ifdef'd out.
This removes the last hack introduced to get the FT code to compile
again.
