The script aa_log_extract_tokens.pl expects the format of the logs from
audit. As we don't have audit in the majority of our images and would like
to extract this information from the journal, remove this script and
replace with a shell function.

A number of tests use the script `run-aa-test`. Add the shell port of this
script to common so that it doesn't need to be replicated in multiple
places.

This script uses `aa_log_extract_tokens.pl`, so pull that into common too.
