Don't require rubocop/rspec/language/node_pattern

The node_pattern file has been removed from rubocop-rspec, and we should
no longer require it.

Also, in rubocop-rspec v3 all the pending cops are now enabled by
default. The `RSpec/FilePath` has been split and
`RSpec/SpecFilePathFormat` can be configured to work instead.
