db_stress: db_stress fails on custom filesystems. (#9352)

Summary:
db_stress listener service always uses default filesystem to operate,
causing it to not recognize custom filesystem (like ZenFS plugin FS).
Pass the env to db_stress listener with the correct filesystem
information, so it can open the user intended filesystem.
