[LTP] [PATCH v2 26/30] ltp-aiodio/dio_{truncate, append}: Convert to runtime

[Cyril Hrubis]

Change the code so that the test runtime is capped at the maximal
runtime allowed for the test, which is set to 30 minutes by default.

The io_append() in common.h has to check for runtime to make this work.
