[ruby/rubygems] Add support for bundle install --no-lock

This allows for the same behavior as including `lockfile false`
in the Gemfile. This allows you to get the behavior without
modifying the Gemfile, which is useful if you do not control the
Gemfile.

This is similar to the --no-lock option already supported by
`gem install -g Gemfile`.
