perf(tar): read files with stream

If no provide stats to `archiver` then stream will be loaded as buffer
(analogue `fs.readFile`).

This slowed the work with large files.

Before this change:

```
real   	1m23.794s
user   	1m26.043s
sys    	0m17.291s
```

After this change:

```
real   	1m7.710s
user   	1m8.288s
sys    	0m6.331s
```
