The manual partitioning setup was already requiring the user to check the ESP flag for the EFI System Partition. Now the autopartitioning also sets it directly (a one-line change). The sgdisk call in the bootloader module is thus no longer necessary (it was only a workaround because kpmcore < 2.1.0 did not support FlagEsp), so remove that snippet. This fixes configurations such as NVME disks where splitting boot_device into boot_device[-1:] and boot_device[:-1] is not the correct split (because the partition gets a 2-letter suffix) (reported by demmm on IRC).
