u-boot needs libssl-dev

[AnthoJack]

When trying to build u-boot from the docker image (created from Dockerfile.env) I ran into the following error

  HOSTCC  tools/aisimage.o
In file included from tools/imagetool.h:24,
                 from tools/aisimage.c:7:
include/image.h:1166:12: fatal error: openssl/evp.h: No such file or directory
 1166 | #  include <openssl/evp.h>
      |            ^~~~~~~~~~~~~~~

It can be solved by installing "libssl-dev". Documentation and dockerfile may be updated to install it

The problem arose with virt32, no idea if the problem is the same with virt64
