DAOS-16662 test: update some tests to use unique dfuse mount

[daltonbohning]

Update some tests to use unique dfuse mount directory by letting the framework generate one.

Remove mount_dir from run_ior_multiple_variants since it is no longer needed and this level of fine control should be handled per test ideally.
