Change the weight of blkio background group

Previous setting is too agressive, so that bg IO processing may
be dealyed too long if there is continuous IO in root (fg) group.
Raise the background weight to avoid critical issue like watchdog.

Test: no restart while filling up the storage
      app launch test still gets benefit with IO busy in bg
