Subject: [PATCH] Fix savedefault with blscfg
The GRUB_SAVEDEFAULT option was ignored on a BLS configuration. Fix it by
making the menu entries populated from the BLS files to call savedefault
if a save_default environment variable has been set to "true".
This variable is set by grub2-mkconfig to the value in GRUB_SAVEDEFAULT.
