add fiddle as an explicit dependency since it will be removed in Ruby 3.5.0

[kryali]

in ruby 3.4.1 I received a new warning from einhorn announcing the removal of fiddle from the standard library

/usr/local/bundle/gems/einhorn-1.0.0/lib/einhorn/prctl_linux.rb:1: warning: /usr/local/lib/ruby/3.4.0/fiddle.rb was loaded from the standard library, but will no longer be part of the default gems starting from Ruby 3.5.0.
You can add fiddle to your Gemfile or gemspec to silence this warning.
Also please contact the author of einhorn-1.0.0 to request adding fiddle into its gemspec.

Feel free to decline this PR if another approach is more appropriate

Lots of failures

[kryali]

@mperham are these CI failures on main already?

revert on my fork fails /~https://github.com/kryali/einhorn/actions/runs/12846878302

[mperham]

Yeah, they're on main already. I'm looking into it but no ETA. Code rot can be tricky to fix.

[mperham]

Ok, I've got all but one test running successfully. The one test fails on every Ruby, I suspect it's a bad test but I don't know enough about what it's trying to verify. /~https://github.com/contribsys/einhorn/actions/runs/12847054762

awesome, thank you for fixing!
