  Update bootloader-functions.sh

https://www.gnu.org/software/grub/manual/grub/grub.html#search
shows "search [--file|--label|--fs-uuid] [--set [var]] [--no-floppy] name"
so I use "--set root --label REARBOOT" to use consistent syntax
instead of "--set=root --label REARBOOT" mixed syntax before
plus consistent 4 spaces indentation in GRUB2 menuentry output.
