DAOS-6965 Test: Increased the SCM size as recent layout change need m…

…ore space with current dataset. (#4928) (#5228)

Test is failing because of SCM size target size is getting low 9MB with dataset.
This test has no requirement to use low size so increase enough so test
should not fail with ENOSPACE.
Updated test to use PCMEM instead of using tmpfs.
