The previous default size of 256KB provided for only 64KB of actual
space for EFI variables, and after accounting for fragmentation, did
not provide enough free space for applying updates, such as for the
UEFI revocation database (DBX). Increasing it to 512KB allows for
192KB space for variables, and allows the UEFI DBX to be updated
properly via fwupd.
TEST=build/boot google/drobit, verify UEFI DBX able to be successfully
updated via fwupd.
