Make string literal to frozen object on gemspec of defulte gems.

  Added following gemspecs.

    * extensions: date, dbm, etc, fiddle, gdbm, sdbm, stringio, strscan, zlib
    * pure ruby libraries: cmath, csv, fileutils, scanf, webrick

  psych and rdoc is out of scope of this commit. I will merge after
  upstream was change to `frozen_string_literal: true`.
