[rubygems/rubygems] Allow --install-dir to be specified together with --user-install
The combination of install-dir and --user-install used to be disabled for no good reason. This even makes problem on Linux distributions such as Fedora, where --user-install is set by default via operating_system.rb.
The --install-dir is already prefered over the --user-install by the implementation, therefore just drop the check.
