Switch PercentLiteralDelimiters to new default

Let's change that to the new rubocop default, which is also the
suggestion in the ruby style guide.

See https://github.com/bbatsov/ruby-style-guide#percent-literal-braces

This was changed in diaspora too, see diaspora/diaspora#7466

It also includes the changes in the code. This was done with
`rubocop --auto-correct` and no we have zero offenses again.
