dash: enable line editting if libedit is selected

Otherwise, explicitly disable it, so that the configure script does not
misdetect a system-installed libedit for example.

Also, add a profile snippet enabling line editing, Emacs style.

[Peter: move DASH_INSTALL_PROFILE inside conditional,
	ensure /etc/profile.d exists]
