LU-13716 tests: skip sanity 205b for older servers

Lustre job stats and sanity test 205b were modified in Lustre
version 2.13.54.91.  When we run version intop testing with
servers less than this version and clients that are greater,
the test will fail.

Skip sanity test 205b for Lustre servers with version less than
2.13.54.91 and client greater than that version.
