entware removes docker binary from path

[fredericrous]

docker binary is removed from the path when we install entware. (at least on TS-451+)

The workaround to this issue is to add to /etc/profile the path to docker (or /opt/etc/profile idk, I did that in both)

export PATH=${PATH}:/usr/local/bin:/share/CACHEDEV1_DATA/.qpkg/container-station/bin

I personally changed my default shell to bash and updated ~/.bash_profile with

source /etc/profile

Side note: Entware could be a second part (/separated) of the guide. The scripts are convenient, but not needed. I personally built my own. Unless scripts are very elaborate, it's more like dotfiles, everyone likes having his own shortcuts
