fault-injection: make some stack filter attrs more readable 

Attributes of stack filter are show as unsigned decimal, such as
'require-start', 'require-end'.  This patch change to show them as
unsigned hexadecimal for more readable.

Before:
  $ echo 0xffffffffc0257000 > /sys/kernel/debug/failslab/require-start
  $ cat /sys/kernel/debug/failslab/require-start
  18446744072638263296

After:
  $ echo 0xffffffffc0257000 > /sys/kernel/debug/failslab/require-start
  $ cat /sys/kernel/debug/failslab/require-start
  0xffffffffc0257000
