playonlinux-bash not put into $PATH

[Li The G No Lie]

After installing playonlinux on Ubuntu 16.04, the `playonlinux-bash` isn't available in the $PATH / `which playonlinux-bash` doesn't find anything.

Further executables are:

/usr/share/playonlinux/playonlinux
/usr/share/playonlinux/playonlinux-bash
/usr/share/playonlinux/playonlinux-pkg
/usr/share/playonlinux/playonlinux-shell

`playonlinux-shell` isn't added either
