Arjun Shankar 29955b5d96 Modify several tests to use test-skeleton.c
This patch modifies several test cases to use test-skeleton.c.
It was generated by a bash script written for this purpose and
thus excludes several other tests which I deemed worth a visual
inspection before making the change.

I intend to follow up with individual patches to the tests
skipped by the script.

The script itself resides at http://git.io/WODAmg and should
reproduce this very patch when run against master.
