disk_qual: disable sysinfo logger hook for StorageFio subtests

When running hardware_StorageFio from another test, disable sysinfo
logger scripts.
Files collected before and after iteration (interupts, meminfo,
slabinfo)... are not collected around the Fio call.

Note that other files still are still collected, those in
site_sysinfo.test_loggables or site_sysinfo.boot_loggables

TEST=Run StorageQualSuspend.quick on samus.
Check where iteration.* directories are missing.
Check there is still overall iteration directory present.
