pathcountgr() is never used except by pathcount(), and neither is the
special case for PATH_WILD. Simplify this and change it into a helper
function that is called by pathcount, and will be used again in a future
patch. Leave count_active_paths alone for the sake of compiler
optimization.
Also use count_active_paths() in mpath_persist.
