Ardunio Fixes relating to internal Intel Galileo Tests

[night1rider]

Changes library setup process to match the recursive style laid out for Arduino IDE 1.5 and newer as described here: https://arduino.github.io/arduino-cli/0.35/library-specification/#libraryproperties-file-format, and Fixed issues regarding internal testing.

I decided to go ahead and update the setup script because to make the old "flat" style library to work we had to put both the src files in the top directory of the created wolfSSL along with a new src folder that contained the same files.
See issue: #6360
I move to the "recursive" style library described by Ardunio "https://arduino.github.io/arduino-cli/0.35/library-specification/#libraryproperties-file-format" for versions 1.5 and newer. Internally we use the 1.8.10 of Ardunio. Changing this makes the file structure similar to how the repo is setup. Only downside is the needing of a src/ folder in the src/ folder.... I also added the generation of a library.properties file as also described in the link above.

Internally Jenkins passes with this new file structure please see the test: nightly-Ardunio-Build-WolfSSL-v2 #76

Jenkins retest this please
