ARM: sheevaplug: unbreak default environment

Commit 1e3d640316 (ARM: sheevaplug: redefine MTDPARTS) changed the mtdparts
part of the default environment, but dropped the trailing zero termination -
So the definition of x_bootcmd_kernel becomes part of the x_bootargs
variable.

Fix it by reintroducing the zero termination.
