test: Always use DejaVu Sans as default font

This makes the results of the test suite more stable across different
environments, because it does not rely anymore on
CAIRO_FONT_FAMILY_DEFAULT (which on Windows is "Arial", on Mac
"Helvetica").

This change should not affect Linux environments, assuming that the
default font is already set to "DejaVu Sans".
