dm-verity-img.bbclass: Stage verity.env file

Browse Source 
Introduce new STAGING_VERITY_DIR variable specific to this bbclass which
defines the directory where the verity.env file is stored during
<DM_VERITY_IMAGE>:do_image_<DM_VERITY_IMAGE_TYPE> task and can
consequtively be picked up into associated initramfs rootfs (which
facilitates executing 'veritysetup' and related actions).

By doing this we mitigate failures that were thus far associated to this
facility, such as

  install: cannot stat '.../build/tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.ext4.verity.env': No such file or directory

and

  install: cannot stat '.../build/tmp/deploy/images/beaglebone-yocto/core-image-minimal-beaglebone-yocto.ext4.verity.env': No such file or directory
