Add the file contents to the GPasteDaemon
A relative file is taken from the caller's working directory, and fails with the g_file_error
getcwd () reports when that cannot be named -- one removed meanwhile. A path that is not valid UTF-8, which a D-Bus string cannot
carry, fails with g_io_error_invalid_data before anything is sent.
