  [FreeType] Do not special case the "sans" font family name

Reviewed by Carlos Garcia Campos.

Do not consider "sans" a generic font family name, as it is not one
according to the CSS spec. This avoids shortcuts in the font matching
algorithm, which leads to picking a better font fallbacks instead if
the FontConfig configuration has odd bits like symbol fonts listed as
preferred in order to make sure symbols (e.g. emoji or PUA glyphs)
from it picked preferably to symbols from the actual font to be used.

* Source/WebCore/platform/graphics/freetype/FontCacheFreeType.cpp:
(WebCore::isCommonlyUsedGenericFamily): Remove match on the "sans" font
family name.
