[LTP] [PATCH 07/13] mem/thp01: Add proper runtime support

[Cyril Hrubis]

The test was executed with -I 120 in all instances. It's cleaner to
define the min_runtime in the test and loop the test function until it's
exhausted.

One of the bonuses we get from this conversion is that the TPASS message
is printed once at the end of the test and we do not flood the logs.
