Change EFI-SYSTEM (#12) from 32MiB to 64MiB in factory_install.

Manatee kernels don't fit since they are >16MiB each and the partition
contains multiple kernels. This partition is already 64MiB in other
images, so this would make the sizes consistent.

BUG=b:185937629
TEST=Build factory images for volteer-manatee and byra-manatee.
