init: use read_file and write_file to implement do_copy builtin
this will make the implementation more cleaner,
and has error message output when failed on some operations
also add the O_TRUNC flag explicitly for the open function
called in write_file.
And add more test on read_file and write_file functions
Test: manual with hikey
