src/open_by_handle: verify dir content only with -r flag

Without -r flag file handles are opened, but file content is not
read.  Treat dir file hanldes, similarly. without -r flag, open dir
file handle, but don't verify its content.

This is going to be used by tests for which dir content is changed
between encode and decode of dir file handle.
