Add '-partition_offset 16' to xorriso parameters

Suggested by Thomas Schmitt, who describes the following benefits:

[-partition_offset 16] will yield a more conventional start of partition 1

  Device Boot Start End Sectors Size Id Type
  test.iso1 64 332111 332648 162.4M cd unknown
  test.iso2 332712 334759 2048 1M ef EFI (FAT-12/16/32)

but also will enable xorriso >= 1.4.8 to let the ISO superblock of
the device claim the range up to the end of partition 2.
So commands like `isosize` will be in sync with the image file

Leave a reminder to switch the el torito image to the appended partition
once we can safely assume a new enough xorriso version.

Use '-e' instead of '--efi-boot' on the xorriso cmdline

This should have no functional change. The surrounding implicit
-eltorito-alt-boot options of --efi-boot are not needed here because we only
have one El Torito image. --efi-boot also implies -no-emul-boot, which we
were passing redundantly. With -e, -no-emul-boot needs to be passed explicitly,
so it is retained in this commit.

Thanks to Thomas Schmitt.

Use '-e' instead of '--efi-boot' on the xorriso cmdline

This should have no functional change. --efi-boot includes several implied
options that we don't need with just the one el torito image. It also implies
-no-emul-boot, which we are already passing anyway (and need to keep with
the switch to -e).

Drop xorriso parameters that have no effect

Passing "-boot-load-size 4" and "-boot-info-table" before "-eltorito-alt-boot"
has no effect. It is likely cruft cargo-culted from x86, just drop it.

Thanks to Thomas Schmitt.
