Ada AA_purge_simulation don't delete R_BUFR files

[mafoipsl]

On ada, purge_simulation don't delete restart files stored in R_BUFR directory on the machine itself.

As a work around, use clean_PeriodLength or clean_latestPackperiod which are deleting all files requested.

It's done like this in AA_clean_PeriodLength :

if [ X${Pack} = Xtrue ] ; then
    echo "Search files with ${PeriodDateEnd} in ${R_BUFR}"
    set +A ListFilesBuf -- $( IGCM_sys_RshMaster "find ${R_BUFR} -name \"*${PeriodDateEnd}*\" " )
    CountListFilesBuf=${#ListFilesBuf[@]}
...
...

This part is missing in AA_purge_simulation.

It's visible when the simulation exit due to permission denied when saving the new restart file

Will replace RshArchive? by RshMaster? in purge and will communicate that we have to do the purge from adapp.
