This indeed what is happening, I'm not sure whether it is a bug or
feature, but you can explicitly ask for primes to come from XITS:
\setmathfont[range=\prime]{xits-math.otf}
(should be after the libertine line)

This is because regular OpenType fonts lack italic correction, and the
only way to include it is by editing the font itself (it is not a hard
job; can be take an hour or in FontForge depending on the number of
glyphs).
