LU-15259 tests: skip acl tests if no bin/daemon users

If the bin/daemon users are not configured on the test system, then
sanity test_103a, test_125, test_154a will fail with:

    $ setfacl -m u:bin:rw f -- failed
    -   ? setfacl: Option -m: Invalid argument near character 3

Skip these tests until they are fixed.
