Add a "Hello JerryScript!" program to the tests
Add a "Hello JerryScript!" program to the tests

The current code base does not contain any "first JavaScript
program" for those who build JerryScript for Linux console. It
does contain a LED-blinking example -- blinky.js -- but that's
only useful on an developer board where LEDs-to-be-blinked are
available. And the rest of the tests are just that: tests, giving
passed/failed information but nothing eye candy.

This patch adds a simple JS script that can act as a warm welcome
to anyone after the first successful build trying to run something
proving that Jerry works.
