xen/misra: xen-analysis.py: Fix latent bug

Currenly there is a latent bug that is not triggered because
the function cppcheck_merge_txt_fragments is called with the
parameter strip_paths having a list of only one element.

The bug is that the split function should not be in the
loop for strip_paths, but one level before, fix it.
