util-linux-ng: fix DEPENDS
* it picks up pam from staging if it's built, so add it to DEPENDS with DISTRO_FEATURES guard
* remove bogus IMAGE_FEATURE check since u-l-ng is supposed to be used in images with or without udev
Recipes are not allowed to make compile decisions based on the image that's going to get built, since that breaks package management severely.
More to the point: What happens when you do 'bitbake util-linux-ng' and later do 'bitbake foo-image' where foo-image sets a different IMAGE_DEV_MANAGER?
