ipatests: Skip ds_encryption tests on RHEL9 SUT.
test_ipahealthcheck_ds_encryption tests are failing
in RHEL9 SUT because in this test tls protocol version
is set to TLS1.0 using the below command, but its
reset to TLS1.2 causing the test to fail.
'dsconf', 'slapd-TESTREALM-TEST', 'security', 'set', '--tls-protocol-min=TLS1.0'
Hence the test is skipped to be run on RHEL9.0 SUT.
