uboot-envtools: update to 2018.03

Several changes has been made:

+ AES support has been removed by
  upstream commit c6831c7 (2017-11-14)
  [remove patch "200-fw_env_no_aes.patch"]

+ Support for UBI volumes has beed added by
  upstream commit 34255b9 (2017-11-15)
  [remove patch "300-support-env-in-ubivol-chardev.patch"]

+ A command line argument has beed added ("-c") to manually indicate
  the location of the environment configuration file

Also, patch "400-u-boot-2015.10-stdint.patch" is no longer
necessary, and the config option to enable UBI support has
been removed.
