load.c: keep encoding of feature name

* file.c (rb_find_file_ext_safe, rb_find_file_safe): default to
  US-ASCII for encdb and transdb.
* load.c (search_required): keep encoding of feature name.  set
  loading path to filesystem encoding.  [Bug #6377][ruby-core:44750]
* ruby.c (add_modules, require_libraries): assume default external
  encoding as well as ARGV.
