Kevin Lubick ec1c620316 Avoid system fonts when fuzzing
This should make reproducing certain fuzzes easier between oss-fuzz
and a typical dev's desktop.

This was the most straight-forward way I could think of to
accomplish this.  An ideal solution would "compile" a set of
fonts that was not the test set and embed it, but I lack the
domain knowledge to craft such a set.

If this method works ok, we can explore making the font set
more robust and varied.
