Update st_archive and lt_archive with multiple bug fixes.

Update st_archive to remove creation of hardlinks between
[comp]/rest and rest/[dname] which caused problems with both
HPSS (duplicate files) and the copying of restart sets. Remove
the DOUT_S_SAVE_EVERY_NTH_RESTART_FILE_SET option in favor of
a different option to select which days of the month to save - not yet
implimented. Test lt_archive with new batch system code and ensure HPSS
queue submission works on YS. Waiting to test on NERSC.

Test suite: ERR.f19_g16.B1850W
Test baseline:  N/A
Test namelist changes: N/A
Test status: bit for bit

Fixes: #308
