lib/test: load test data files with suffix "_test.txt"

Previously, the LoadDataDir load all files from directory that have
".txt" extension.
This may cause unknown non-test data files loaded and may cause an error.

To distinguish it with other text files, inside the directory to be loaded
load only the file that has suffix "_test.txt".
