exp/font: droid->noto fallback in tests
The Droid font has been superseeded by the Noto family upstream in
Android. This resulted in Debian and inherently Ubuntu too dropping
support for the first in favor of the latter. This CL ensures that
tests will pass on both older and newer debian based distros.
