LU-16945 tests: skip sanity test_27Cg in interop

Sanity test_27Cg is testing functionality that was broken in older
MDS versions, but does not have a version check, so it causes testing
to timeout 100% of the time when running on older servers.  Skip it.

Fixes: d96b98ee6b63 ("LU-16693 lod: ENODEV on setstripe with wrong OST#")
Test-Parameters: trivial testlist=sanity env=ONLY=27Cg
