u-boot: gru: Do not persist EFI variables

By default U-Boot stores EFI variables in a ubootefi.var file in
whatever EFI System Partition it finds, which would be a FAT filesystem.
I'm occasionally finding out while testing that my ESPs somehow end up
with a corrupted filesystem, and I'm suspecting it's this.

For now, disable storing EFI environment variables on disk so that
U-Boot doesn't try to manipulate the filesystem.
