LU-13031 tests: skip sanity/test_205h,205i in interop

Skip sanity tests 205h and 205i when the MDS version is too old
to have the jobid xattr changes. Fix test 103a to not try to set
the job_xattr parameter when it does not exist.

Fixes: 23a2db28dcf1 ("LU-13031 jobstats: store jobid in xattr when files are created")
Test-Parameters: trivial testlist=sanity env=ONLY="103a 205h 205i"
