Log:
[ruby/rubygems] Add a missing "require 'etc'" statement:

- Ref https://github.com/ruby/rubygems/pull/9171#discussion_r2658056892
- Referencing the constant Etc may raise a `NameError` depending on
whether other Rubygems/Bundler codepath have evaluated a prior
"require 'etc'". This can be reproduced with this Gemfile:

```ruby
source "https://rubygems.org"

gem 'prism', github: "ruby/prism"
```
