New port: textproc/erlang-syntaxerl: Syntax checker for Erlang

SyntaxErl is a syntax checker tool for Erlang. The syntax checker currently
supports Erlang source files (.erl), Erlang header files (.hrl), Erlang
configs (.config, .rel, .script, .app, .app.src), Escript files (.erl,
.escript, .es), leex files (.xrl), and yecc files (.yrl). Its main purpose
is to be used by tools like Emacs's Flymake and Vim's Syntastic or ALE.
