cryptsetup: add libdevmapper to RDEPENDS

Since commit [libdevmapper/lvm2: force recipe libdevmapper to populate
sysroot only] applied, if recipe DEPENDS on libdevmapper, we have to
add it to packages RDEPENDS to fix [file-rdeps] QA issue

Set PREFERRED_RPROVIDER_libdevmapper = "lvm2" in layer.conf to explicit
RDEPENDS on libdevmapper in cryptsetup
