Building EFI partition for 32-bit anyboot ISO image was disabled
in hrev52443 to fix issue #14656.
As haiku_loader.efi is now available for the x86 architecture
since hrev55917, we can re-enable building EFI system partition
for the 32-bit ISO.
We can also remove the build rules related to HAIKU_ANYBOOT_LEGACY
as it is not used any more.
