Subject: [PATCH 216/216] Only attempt to scan different BLS directories on EFI
 machines

Current BLS support attempted to scan for BLS directories, but this only
makes sense on EFI, where BLS fragments are in /loader/$vendor/entries.

For BIOS, only either the default /loader/entries path should be scanned
or the BLS directory defined in the blsdir GRUB 2 environment variable.
