Fix #302: Test suite fails with freetype 2.7
Actually, the test failures are not necessarily related to freetype
2.7, but rather are caused by subpixel hinting which is enabled by
default in freetype 2.7. Subpixel hinting is, however, already
available in freetype 2.5 and in versions having the "Infinality"
patch.
To get the expected results in all environments, we have to disable
subpixel hinting, what is easily done by setting a respective
environment variable.
