systemd: bump to version 221

- Bump to version 221
- Update hash file

- Add --disable-gnuefi to configure options to avoid a failure like this
  one:

  checking for /usr/lib/gnuefi/elf_ia32_efi.lds... configure: error:
  cannot check for file existence when cross compiling

- Remove gudev logic since it has been removed from the systemd tree and
  it is now an external project.
