package/makedevs: fix recursive chmod

Browse Source 
The logic implemented in e745c0b to stop makedevs from recursively running
chmod() on dangling symlinks excluded everything that isn't a symlink.
Other file types or directories are skipped/ignored.

Logic has been updated to exit the function if mode shouldn't be changed
or if path is a dangling symlink.
