devel/ruby-sexp-processor: update to 4.12.0

=== 4.12.0 / 2019-03-12

* 3 bug fixes:

  * Fixed sexp_body to return empty sexp instead of nil when using STRICT_SEXP.
  * STRICT_SEXP=4+ fails w/ current use of concat. Removed concat from \ 
strictness for now.
  * Use concat internally instead of splat. Some people have 20000 node sexps! \
