Subject: A patch series improving data quality of perf test for CoreSight

This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code to
allow this and centralize the shell script finding into one location and
only one single scan that builds a list of all the found tests in memory
instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass
of opening files). It also more cleanly filters scripts to see only
*.sh files thus skipping random other files in directories like *~
backup files, other random junk/data files that may appear and the
scripts must be executable to make the cut (this ensures the script
lib dir is not seen as scripts to run). This avoids perf test running
previous older versions of test scripts that are editor backup files
as well as skipping perf.data files that may appear and so on.
