LU-10680 tests: fix interop for sanity test_160h

Add a check sanity test_160h whether /sbin/umount.lustre is installed
on the MDS, since this subtest is checking whether the MDS unmount
process has completed, and otherwise fails during interop testing.

Test-Parameters: testlist=sanity env=ONLY=160 serverversion=2.12
Fixes: 31fef6845e8b ("LU-10680 mdd: create gc thread when no current transaction")
