x86: zimage: Update cmdline parameter to be an env var
With the updated changes to bootargs substitution[1], the zboot command
needs to be updated to get its command line from an environment variable
instead of a memory address. This is because the command-line string must
be updated to convert %U to ${uuid}, etc.
In any case it is more flexible to use a environment variable and it is
best to do this before the release to avoid a subsequent change.
Update the command accordingly.
