Subject: [PATCH] Improve example REPL to exit if there is nothing on the stdin
 (#3193)

When reading from the stdin a '\n' character or an empty line/file
was expected to end the read. However, in case of an input which is not terminated
with a newline a buffer overflow will occur.

Test case:
```sh
$ echo -n "print('a')" | ./build/bin/jerry
```
