Title: Add option to skip installation when overriding installation directory.

Add option --no-skip-override (-o) to avoid reinstalling Ruby if already present (actually, if specified installation directory already exists).
I think this is a nice feature to have, especially when throwing a ruby-install command into a script used for CI.
