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.
