[oe] [meta-oe][PATCH] cryptsetup: Don't enable udev for native build

[Robert Joslyn]

When building cryptsetup-native, don't enable udev support since there
is not a udev-native recipe.

When udev is enabled, change the dependency from a DEPENDS to an
RDEPENDS. The --enable-udev option adds a runtime check for udev before
using udev features of libdevmapper. Because of this, udev isn't needed
at build time, just runtime.
