elementary: always use a font that matches our expectation for our test instead of the system one.

Summary:
Our tests do rely on the font to have certain characteristic so that they have the value and the
item size being calculated is the one we expect. As it is quite hard to support an infinite number
of font with random size, it is easier to embed one we can rely on for our test. I have copied Vera
from Expedite and changed evas global font path to look for it first. After this patch, even with an
incompatible font in the system, it does still pass all tests. This add around 400KB of data to our
git, but is necessary for a reliable tests suite.
