LU-14323 tests: skip sanity-flr/pfl tests for older servers

sanity-flr test 46 sub tests 7, 8, 9 and 10 and sanity-pfl
test 16c were added to lustre-master version 2.13.53.205.
When we run version interop testing, these sanity-flr and
sanity-pfl tests will fail.  Thus skip sanity-flr test 46
subtests 7, 8, 9, and 10 and sanity-pfl test 16c when run
with servers with version less than 2.13.53.205 and clients
with later version.
