base-files: coreutil-sha256sum breaks status code

With package "coreutil-sha256sum" installed "sysupgrade" fails to perform 'sha256sum -s' and instead returns 'invalid option -- 's''.
This is caused due to:
	different syntax for a sha256sum status check ('sha256sum --status' with "coreutil-sha256sum")
	'/usr/bin/sha256sum' being symlinked to '/usr/bin/gnu-sha256sum' (after installation of "coreutil-sha256sum")
"coreutil-sha256sum" package from the packages feed replaces the Busybox sha256sum
This patch restores for 'sysupgrade' the busybox call to its sha256sum applet.
