Enabled Arduino verification build.

Enabled Arduino verification build.

During the latest merge of connectivity-abstraction branch into master branch,
the Arduino verification process was disabled in order to properly verify all other code paths on the build system post-merge to enable all IoTivity
contributors' work for post-merge efforts. This changeset allows for post-
merge efforts to continue as well as continuing verification of Arduino
code paths.
