ipatests: fix test_idp

The test is calling su -c "sudo yum list yum" keycloakuser
to ensure that keycloakuser is allowed to execute the yum command.

On fedora 42 and above, the yum package does not exist any more.
Replace with a call to yum list sssd-client as the package
sssd-client is always installed on our test machines.
