Make arguments given with -s option to erl aware of file name encoding
OTP-10702 Arguments to functions started with the -s option to erl were converted to atoms with list_to_atom(binary_to_list(Bin)) and thus were always seen as latin1 encoded. For other arguments to erl the conversion (to string) would take into account the file name translation mode (set with +fnl, +fnu or +fna switch to erl) and try to convert using unicode:characters_to_list/2. The reason behind this is that it must be possible to give paths and filenames on the command line and get the expected encoding. With the same reasoning, this commit changes the behaviour for arguments to functions started with the -s option to also take into account the file name translation mode. The arguments are now converted to atoms by list_to_atom(unicode:characters_to_list(Bin,file:native_name_encoding())
