Adam Duskett 9c52d4bee6 mender-grubenv: new package
Mender-grubenv contains the boot scripts and tools used by Mender to
integrate with the Grub2 bootloader.

The user must select the following Grub modules for this package:
loadenv, hashsum, echo, halt, gcry_sha256, and test.

Because this patch also includes a grub version of fw_printenv and fw_setenv,
package/mender/Config.in must be changed as well at the same time, because if
both uboot-tools and this package are selected, during startup, mender calls
the uboot-tools version of fw_printenv and fails to start.

[Arnout:
 - reorder depends clauses;
 - add runtime tag to grub2 dependency
 - remove wchar dependency from comment
 - only error if BR_BUILDING
 - use install instead of cp for a single file.]
