Regression: ufo2ft 2.25.0 rejects extra keyword arguments passed by fontmake

[rschiang]

Starting from ufo2ft==2.25.0, the library will start to reject any unexpected arguments (googlefonts/ufo2ft@c87320c).

The current version of font_project.make_variable_font(), however, passes two of the arguments (flattenComponents, cubicConversionError) that are only meant to be used with ufo2ft.compileTTF but not ufo2ft.compileVariableTTF.

We’ll need to either prune the excess arguments or update ufo2ft to accept them.

Sorry yes, thanks. Ufo2ft needs to continue accepting the arguments, I'll fix it.

Upstream issue is googlefonts/ufo2ft#551

bumped minimum ufo2ft to 2.25.1 in 61b0641 -- which should fix this among other things
