[LTP] [PATCH] tst_kconfig: Don't consider CONFIG_FAULT_INJECTION slow

But it's default off. If one enables it, it could also increase LTP_RUNTIME_MUL.
IMHO the only effect now is 4* longer timeout on a kernel bug which freezes test
running.

Do you mean to look if /sys/kernel/debug/fail*/verbose exist and contain 2?

Kind regards,
