Subject: [PATCH 217/220] Only mark GRUB as BLS supported in OSTree systems
 with a boot partition

The script grub2-switch-to-blscfg updates the grub2 EFI binary in OSTree
systems and marks that has BLS support, to indicate that's not necessary
to add menuentry commands since the BLS snippets can be used to populate
the GRUB boot menu.

But OSTree doesn't support installations that don't have a boot partition,
the BLS snippets assume that there will be one so this has to be checked
and only mark the bootloader as supporting BLS in OSTree installations
that have /boot as a mountpoint.
