DRW: Curve: Fix wrong UBO alignment

This was preventing correct attribute rendering with multiple attributes.
Since the `CurveInfos` struct is used for data sharing between C++ and
GLSL and inside a UBO it needs to obey the `std140` alignment rules which
states that arrays of scalars are padded to the size of `vec4` for each
array entry.
