[eruby] Add GetCommand to erb linter
GetCommand conditionally adds a filter (implemented as inline Ruby code in the command line) to transform some of the problematic Rails-specific eRuby syntax. Specifically, <%= tags are replaced with <%. This does not reduce the effectiveness of the linter, because the transformed code is still evaluated. This solution was suggested by @rgo at https://github.com/w0rp/ale/issues/580#issuecomment-337676607.
