Increase factory shim EFI partition size

Browse Source 
With recent changes (transitioning to 64 bit x86 kernels and the 3.2
kernel) the factory install image EFI partition gets overflown,
resulting in build failures.

This change makes sure that factory shim image gets allocated twice
the room for the EFI partition (32M).

BUG=chromium-os:27639
TEST=manual
  run the following commands while in chroot:
  cd ~/trunk/src/scripts
   ./build_image --board=lumpy
   ./build_image --board=lumpy --replace --symlink=factory_shim --build_attempt=3 factory_install
   cd ~/trunk/src/build/images/lumpy/factory_shim
   ./unpack_partitions.sh factory_install_shim.bin
   ls -l part12
   cd ~/trunk/src/build/images/lumpy/latest
   ./unpack_partitions.sh chromiumos_image.bin
   ls -l part12

 . observe that in factory shim case the part_12 partition size is
   33554432 bytes, and in the regular image case the part_12
   partition size is 16777216

 . try using the factory_shim USB stick in recovery mode, observe the
   system come up (did not have a server set up, so the full install
   process was not verified).
