With the goal of centralizing all tests in the system, this is a
first step to establish a Tests sub-tree. It will contain all of
the unit tests and test harnesses for the various components in the
system.
When attempting to fix the dirent code I also changed
this to use strlcpy instead of the custom string copy
loop that was there before. Looking over strlcpy it
looked like it should work when using a non null terminated
string, I obviously misinterpreted the implementation
as it will read till it finds a null terminator.
Manually null terminate the string to address this.
Gunnar found this after he fixed UserspaceEmulator.
I reproduced it locally using his branch, and also
found the memory leak I had in the unit test for the
scandir that I added, so lets fix that as well.

I ran into a need for this when running stress-ng against the system.
This change implements the full functionality of scandir, where it
accepts a selection callback, as well as a comparison callback.
These can be used to trim and sort the entries from the directory
that we are being asked to enumerate. A test was also included to
validate the new functionality.
