[PATCH 14/14] toaster: insure IMAGE_INSTALL_append values have a space prefix

[Alex DAMIAN <alexandru.damian@intel.com>]

From: David Reyna <David.Reyna@windriver.com>

When the IMAGE_INSTALL_append value is not empty, it must have a space prefix
in order for the "append" operator to concatenate the values correctly, so we
enforce it in this variable's submit javascript.
