[LTP] [PATCH V3] lib: redefine the overall timeout logic of test

[Cyril Hrubis]

Hi!
> Notes:
>     Changes V2 --> V3:
>     	* Improve timeout description based on Cyril's suggestion
>     	* Move .runtime to .timeout for some tests (fsplough, ksm02, ksm04)
>     	* Drop the changes on shell test test_timeout.sh
>     	* Squash tst_set_timeout and set_mempolicy01 patches into the first one
>     	* Double the duration of a single test iteration on an RPi4 and use that
>     	  value to set .timeout for readahead02 test

Here you say timeout

But you actually set runtime instead.
