Add precheck() fun

Checking env before run testsuite is necessary.
1. Add common check in agl_test_base.py.
It is currently an empty function.
If necessary, common check sould be added.

2. Add ptest common check in agl_test_ptest_base.py.
For ptest testsuite, check whether ptest-runner and run-ptest script exist.

3. Add special check in run_tests.py.
For aio-stress testsuite, check whether compiled aio-stress script exists
For bzip2 testsuite, check whether bzip2 cmd exists.
