Subject: [PATCH] Include OSTree path when searching kernels images if BLS
 config is enabled

The OSTree based distros (i.e: Fedora Atomic) don't install kernel images
in the /boot directory, but in /boot/ostree. So the 10_linux script isn't
able to include these kernels in its list, so the linux_entry() function
is never called.

This isn't a problem since the 10_linux script isn't used to populate the
menu entries anyways, but instead a custom 15_ostree script is used. But
for BLS we want the 10_linux script to generate the minimal grub.cfg that
calls the blscfg command, so add the OSTree kernel images to the list.
