LU-9024 tests: improve conf-sanity test_63 output

Improve the output of conf-sanity.sh test_63 to fix SLES11
test failures caused by different /proc/slabinfo results.
Replace "ldisk" with "ldiskfs".

Load ldiskfs module on the MDS if test is run with ONLY=63.
Compute number of slab entries per page even if the slab
is using multiple pages to improve object efficiency.
