Dockerfiles add screen for devshell

[cbugk]

While trying to run devshell (bitbake -c devshell virtual/kernel) got error:

NOTE: Executing Tasks

TMUX and Screen are the two applicaple options in that order of priority. I chose screen out of preference, however, tmux could also be used. This fixes devshell access (the ordinary ^A+D to detach etc.)

Apparently the command I should have actually used is bitbake linux-imx -c menuconfig. Nonetheless, essentially same error is printed out:
