Use mutable strings for mutation tests.
* test/fiddle/test_func.rb (test_string): this test break String buffer by `strcpy` ("000" -> "123"). However, the string literal "000" with `frozen_string_literal: true` returns a string object from frozen string pool. So that after this test "000" from fstring pool becomes "123" (modified string). 'test/date/' uses "000" (as fstring) and tests are fails (we could check with `make test-all TESTS='fiddle date'`). * test/fiddle/test_function.rb: ditto. * test/fiddle/test_import.rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59861 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
