tests(slurm_ops): update mocks in unit tests to new package commands

Adds additional test as well to ensure that `/var/lib/slurm`
has the correct file permissions mode if created by the
`charms.hpc_libs.v0.slurm_ops._AptManager._create_state_save_location`
method after the relevant Slurm daemon has been installed.
