u-boot: Increase EFI variable buffer size 

Debian's signed shim allocates too many EFI variables to fit in the EFI
variable memory buffer. Normally it would then try to continue booting
in non-secure-boot mode, but its error handling throws a synchronous
abort that reboots the board, making it impossible to boot into Debian
unless one manually loads GRUB instead of shim. Increase EFI variable
buffer size to avoid triggering the bug.
