Subject: [PATCH] Don't update the cmdline when generating legacy menuentry

 commands

On OPAL ppc64le machines with an old petitboot version that doesn't have

support to parse BLS snippets, the grub2-mkconfig script is executed to

generate menuentry commands from the BLS snippets.

In this case, the script is executed with the --no-grubenv-update option

that indicates that no side effects should happen when running the script.

But the options field in the BLS snippets are updated regardless, only do

the update if --no-grubenv-update was not used.
