EX-7596 tests: disable metadata_csum_seed for pcc cache device

latest e2fsprogs enable metadata_csum_seed feature when mkfs.ext4
a device, which is used in pcc test as a cache device. Such a ext4
fs cannot be mounted on an old kernel of el7. So disable this
feature for pcc cache device if it is detected in sanity-pcc test.
