module: Make module_flags_taint() accept a module's taints bitmap and usable outside core code

No functional change.

The purpose of this patch is to modify module_flags_taint() to accept
a module's taints bitmap as a parameter and modifies all users
accordingly. Furthermore, it is now possible to access a given
module's taint flags data outside of non-essential code yet does
remain for internal use only.

This is in preparation for module unload taint tracking support.
