app/test: reduce duration of red functional test

'red_autotest' changed to run only functional tests without test #4 which was
taking ~53 seconds. 'red_autotest' takes ~2[s] now.
'red_perf' has been added to run performance tests only).
'red_all' has been added to run all functional tests (including #4) and
perfromance tests. This reflects current 'red_autotest' behavior.

Other changes:
- machine TSC clock frequency detection takes place only once now.
- timeouts and number of iterations in functional tests have been reduced
  in order to shorten test duration.
