Subject: apps: lc-compliance: Re-organize source directory

Before adding more tests and more helper classes to lc-compliance,
reorganize the source tree to split test and helpers in two separate
directories.

While at it, rename the 'SimpleCapture' class and its derived classes to
just 'Capture'. Rename the source files accordingly.

Re-sort headers inclusions to please checkstyle.py too.
