Remove *mirror_output* functions

This is a partial revert of 7d80bb63583f ("ART: Add
'--rerun-failed-tests' option").

There is no user of the *mirror_output* functions since
293eacffcdb9 ("Refactoring functions in test_art_target.sh").
Since these functions introduce unnecessary complications in
start_logging, let's remove them.
