I don't think anyone uses this neologism outside of a poem or an irony, because on top of that it can be considered racist. In principle it would be "someone who loves the ebony tree or its wood", but as it has a very dark and characteristic black color, in America it was said ironically that African slave traders were "importers of ebony"; and from there comes the definition provided by colleague Alberto, to compare the color of wood with that of the skin of people (men and women) with African origins. The rest of the meaning is provided by the suffix -filo, which is interpreted not only as an affection or hobby but also as a sexual inclination towards something or someone taken as an object.
