[LTP] [PATCH] tst_test.sh: Use $LTP_TIMEOUT_MUL also in TST_RETRY_FN_EXP_BACKOFF()

[Li Wang]

Hi Petr,

If timeout occurred in the exp backoff macro, we could pass a bit more time
to it and use prototype directly.

    e.g.   TST_RETRY_FN_EXP_BACKOFF "$1" "$2" "more_time"

And yes, we actually can't guarantee a proper time value for all kinds of
platforms. So I agree on involve $LTP_TIMEOUT_MUL to exp backoff macro.

Btw, shouldn't we also apply this change to the C prototype too?

"..., try exporting LTP_TIMEOUT_MUL > 1" ?
