Docker: Cleanup docker process interface

Instead of creating the actual command in two places
this change moves everything into one function.

Instead of sending the environment and working directory
into the shell as arguments, we send it via the correct
docker exec cli arguments.

Instead of creating QStringLists and adding them
to a CommandLine we directly add them to the
CommandLine instead.

This also fixes an issue when the working directory
contains spaces.
