* hash.c (rb_f_getenv): use rb_filesystem_str_new_cstr

  instead of rb_str_new2.
  ENV['PATH'].encoding should be Filesystem Encoding
  because its content is related to filesystem.
  see [ruby-dev:39393]

* hash.c (env_fetch): ditto.

* string.c (rb_filesystem_str_new): defined.

* string.c (rb_filesystem_str_new_cstr): ditto.

* include/ruby/intern.h (rb_filesystem_str_new): added.

* include/ruby/intern.h (rb_filesystem_str_new_cstr): ditto.
